The Run/Hold key determines whether the FieldFox sweeps continuously or does NOT sweep, but holds the display results of the last sweep that was performed.
Use Hold to conserve battery power or to allow you to save or analyze the results of a specific measurement sweep.
The current sweep mode is shown on the screen as:
— Continuous
—Hold
—
is displayed while a single sweep occurs.
How to perform a single sweep while in Hold
1.Press Sweep 3.
2.Then choose one of the following:
—Single Automatically sets Continuous OFF (Hold) and causes FieldFox to make ONE measurement sweep, then hold for the next Single key press.
—SA Mode ONLY – With Continuous OFF each successive Run/Hold press also causes a single sweep.
—Continuous ON OFF Makes continuous sweeps. This is the typical setting when battery power is not critical.
The Preset key restores the FieldFox measurement settings to a known condition. You can preset the entire instrument, or just the current Mode (CAT, SA, and so forth).

Then choose one of the following:
—Mapping – (Requires Option 352) opens a menu of softkeys that enables the Indoor / Outdoor on–the–box mapping features. Refer to Chapter 16, “Indoor and Outdoor Mapping – Option 352 (Requires Spectrum Analyzer Mode (Option 233), and GPS Receiver (Option 307)).”
—EMF Antennas – opens a menu of softkeys that enables the triaxial antenna feature, for use in EMF measurements. Refer to Chapter 15, “USB Antennas – Full Capability Requires EMF Option 358, and either SA mode (Option 233 Mixed Analyzers) or OTA—LTE FDD (Option 370), LTE TDD (Option 371), 5G NR / 5G NR EVM Conducted / 5G TF (Option 378).”
—Freq Extnd – opens a menu of softkeys that enables frequency extender feature, for use with VDI and OML heads. Refer to “How to view and change the Frequency Extender (Freq Extnd) Settings” on page 863.
| IMPORTANT! The Frequency Extender (Freq Extnd) is only active (available) when one of the following modes are enabled: SA/RTSA/IQA/OTA/VSA (via the Remote Server feature). When VDI and OML millimeterwave extenders are used, Cable and Antenna corrections, if On, are included in eCorr, or Extended Corrections. |
| The OML millimeterwave extenders has been discontinued and are no longer supported. Keysight recommends VDI as the preferred alternative. For more information on the supported Keysight VDI frequency extender modules, please visit: https://www.keysight.com/us/en/product/N9910XVDI/mmwave-frequency-extenders-for-fieldfox-handheld-analyzers.html |
How to view and change the Frequency Extender (Freq Extnd) Settings
The following are the only supported modes for the frequency extender feature: SA (Option 233), mixed analyzers, RTSA (Option 350), IQA (Option 351), OTA (Option 370/378), and VSA (via the Remote Server feature). IMPORTANT! When using a frequency extender with the FieldFox you need to manually set the LO power: – When using the mixer, the LO power should be reduced to –12 dBm and – Reduce frequency span to make measurements until the “unleveled power” message goes away (requires ≥A.12.40 firmware) IMPORTANT! Due to limitations in the OML hardware, the heads have a 6 GHz frequency span. Examples Using a 24 to 40 GHz mixer, you can sweep: —24 to 30 GHz and 25 to 31 GHz, but not —24 to 31 GHz Assuming the same 24 to 40 GHz mixer, using OTA mode, you can —Set a CC0 to 24 GHz and CC1 to 31 GHz, but not —CC0 to 4 GHz and CC1 to 32 GHz, because you have to remain within the mixer’s band 89600 VSA (via the Remote Server feature) are compatible with the frequency converter heads, but cannot apply or edit the frequency head corrections.
If you upgrade your FieldFox firmware to ≥A.12.40, but find you are unable to adjust the LO power level to –12 dBm, refer to “Erase User Data” on page 904.
For this section, refer to Figure 31-1 on page 867, Figure 31-2 on page 868, Figure 31-3 on page 868, Figure 31-4 on page 869, Figure 31-5 on page 869, and Figure 31-6 on page 870.
These settings are used to set up a frequency extender head (e.g., VDI, OML head). The frequency extender feature can be used in OTA FR2 measurements. See also, Chapter 13, “Over–the–Air Measurements (OTA) – LTE FDD Option 370, LTE TDD Option 371, 5G NR / 5G NR EVM Conducted / 5G TF Option 378.”
The frequency extender heads are an external down converter that extends the FieldFox's range. The frequency extender head makes use of the FieldFox's source and uses USB port for power. The FieldFox support for the frequency extender head includes:
— The frequency extender heads are compatible with to SA, IQA, OTA, RTSA, and 89600 VSA (via the Remote Server feature—with VSA license). The OML frequency extenders have approximately 4 to 10 dB of gain depending on the mixer and frequency.
—The USB ports are used to supply power to the head
—Port 1 is used to supply an LO signal to the head. The LO signal is automatically generated, using the internal source. Therefore the application disables normal Port 1 access to the internal source. But, automatic alignments of the SA Receiver still remain active using an internal path for the source.
—Port 2 is where the head delivers the downconverted signal to the SA receiver.
—High Sensitivity ON OFF selection: able to choose between showing largest span (wide) available (6 GHz) or best noise floor (narrow).
Frequency Extender Procedure:
General Comment on Frequency Converter Usage:
OML heads are limited to 6 GHz span.
Example:
If you are using a 24–40 GHz OML head you can sweep:
—24–30 GHz and 25–31 GHz, but not:
—24–31 GHz
But, in OTA mode, because each frequency is set separately, you can set CC0 to 24 GHz and CC1 to 31 GHz.
But, you cannot set CC0 to 4 GHz and CC1 to 32 GHz. You have to stay within the band of the OML mixer (24-40 in this example), if you are enabling an external head.
1.Press System 7 > Utilities > Freq Extnd > Select Freq Extnd Head
2.To select the frequency extender head, use the numeric keypad, arrows, or rotary knob to change the value.
3.Press Recall File to make the highlighted head the current selection.
4.Press Freq Extnd ON OFF to ON to enable the frequency extender head. When a compatible mode is enabled, all supported modes annotate Freq Extnd at the bottom of the display. See also, step 8.
5.Optional: Press High Sensitivity ON OFF OFF is selected for maximum span (up to 6 GHz). Narrow is selected for lowest noise floor for a given RF input (100 MHz). Default is OFF (maximum span – 6 GHz).
6.Optional: Press Setup Corr Auto Edit SA when Auto is selected the default corrections for a frequency converter head are automatically loaded ("...Default.csv"). These corrections are defaults for the specific head, to improve nominal accuracy of the amplitude readings, but this accuracy is not specified. Press Edit SA, when you want to view or edit the corrections using the SA mode corrections. This state stops all auto-loading of the default corrections. Refer to step 8.
The other non-SA supported modes do not allow viewing or editing of the corrections, but they all share the same corrections.
Therefore, any manual changes to the corrections (using SA via Edit SA) are then used by other supported modes (RTSA/IQA/OTA) as well.
7.Optional: Press Apply Corr ON OFF OFF is selected to not apply the default nominal file corrections. Press to apply corrections for the Converter, all supported modes will apply corrections and annotate "eCorr" in the left panel. The corrections applied (regardless of mode) are either default/nominal (if Auto loading was used) or custom/specific (if manual editing Edit SA was used). Default is OFF.
8.Press Mode > and then your preferred mode for testing.
IMPORTANT! The softkey menu for editing of the frequency converter correction files is only available when the FieldFox is in SA mode. |
—Optional: If you pressed Edit SA in step 6 above and want to display and to edit a "*.csv" corrections file then:

GNSS (GPS+) and GPS IMPORTANT! The FieldFox may display "Ant OPEN", even when a GPS antenna is connected to the FieldFox. If the GPS antenna is powered by another power supply and has a DC blocking capacitor where the feed is connected to FieldFox, then minimal amounts of current will be drawn from the FieldFox, so the instrument will display "Ant OPEN". The threshold to detect the presence of an antenna is approximately 1.6 mA.
GPS (Global Positioning System) allows you to ‘stamp’ each data trace with your physical position in latitude/longitude/elevation format. This can be useful when making measurements on cell towers or other antennas at remote locations.
—With Option 307, GPS is available with the built-in receiver accessed through the top-panel SMA (f) connector. This connector has a settable 3.3 VDC or 5 VDC bias voltage which is switched ON when GPS is set to Internal. This system is designed for use with an active antenna such as the Keysight N9910X-825.
—Without Option 307, GPS is usable ONLY with an external GPS receiver that is shipped with Microsoft “Streets and Trips” and “AutoRoute”. The GPS receiver is NOT available from Keysight. Only the GPS USB receiver is used with the FieldFox. Therefore, it is NOT necessary to purchase the very latest version of the map software.
GPS settings are the same with, or without, Option 307.
Your GPS settings can be saved with Preferences. Learn more in “Quick Settings Table” on page 870.
1.Press System 7 > System Configuration > GPS
2.Then choose from the following:
3.Display ON OFF Enable and disable the GPS display on the FieldFox main window.
4.GPS then choose from:
—OFF - Disable GPS (default setting).
—External - Enable GPS using an external, customer-supplied, USB dongle device. A check is made to detect a USB GPS device at the USB connectors.
—Internal - Enable GPS using Option 307 – Built-in GPS. Connect a GPS antenna to the top-panel GPS connector. Learn more about additional GPS antenna accessories at http://www.keysight.com/find/fieldfox. Internal is set automatically when Frequency Reference Source is set to GPS. Learn more in “Frequency Reference Source” on page 890.
When Internal or External is selected, a search is made for satellites overhead. GPS works best when outdoors and in full view of the open sky. When several satellites are found, the following screen appears (when Display is set to ON) and is updated frequently:
| As the bar graph count exceeds 9 bars, the “dB” text is dropped from the number displayed on the bar. Units for C/No are dBHz. |
Figure 31-8 GPS Display
—The left portion of the screen displays satellites and the corresponding number on the adjacent Satellite Power chart.
—The right portion of the screen displays Satellite Power Carrier to Noise (C/No) dBHz values on the tops of the satellite power chart.
| The C/No values returned are not calibrated at the factory or warranted for accuracy. The numbers retrieved are passed unprocessed directly from the GPS receiver in use. |
GPS Status
With GPS enabled the following is displayed at the top of the FieldFox screen:
The following icons (located in RED circle above) indicate the GPS lock status:
- GPS ON and locked on satellites.
- GPS ON, but NOT locked on satellites.
- GPS ON, but no GPS receiver is present or detected.
The following annotation (BLUE circle in above image) indicates the INTERNAL, top-panel antenna status:
—Ant: INIT – antenna status initializing.
—Ant: OK – antenna present and working.
—Ant: OPEN – antenna is not drawing DC bias current. This could occur when an active antenna is not connected properly or the antenna does not require DC bias current. Antennas that do not require bias current can still provide an accurate GPS reading.
—Ant: SHORT – antenna center pin has been shorted to ground. The internal bias circuitry is disabled for about one minute, then re-enabled. You can also press GPS OFF, then GPS Internal to quickly re-enable the antenna bias.

The FieldFox internal frequency reference source is used to make accurate and stable measurements. To improve measurement accuracy and stability, you can use a highly-stable external 10 MHz reference source or a precision timing signal provided with Built-in GPS (Opt. 307).
The Frequency Reference setting will survive a Factory Preset or Mode Preset and is saved as part of the Instrument State. When resuming after Standby, the FieldFox will display an Unlock message while it acquires a lock to an external or GPS source.
How to select Frequency Reference Source
1.Press System 7 > System Configuration > Frequency Ref > Freq Ref Source then
2.Then choose from the following:
—Int Internal frequency reference.
—Ext External frequency reference. Connect the 10 MHz External Reference to the Ref In/Trig In SMA (f) connector on the FieldFox top panel. The FieldFox may take up to 10 seconds to lock to a valid External Reference source.
—GPS Available ONLY with Built-in GPS (Opt. 307). When selected, the internal GPS is immediately enabled and a search for satellites begins. When satellites are found, the precision timing signal is NOT used directly, but is used to correct the absolute frequency of the internal reference many times per second.
Hold-over mode
When the GPS signal is lost, the last GPS reading is used as a hold-over correction value for the internal reference. The hold-over correction value is no longer used, but instead the factory-set correction value is used, when any of the following occur:
—when GPS is disabled.
—when Reference Source is set to Internal.
—when the FieldFox resumes from Standby mode or shut down.
Frequency Reference Status
When switched to Ext or GPS, one of the following annotations appears in the lower-left corner of the screen:
—EXT R – External reference is selected.
—GPS R – GPS reference is selected.
—GPS H – Internal Reference is used with last ‘hold-over’ correction reading.
If the FieldFox does NOT find an appropriate Ext or GPS reference signal, then Ext Ref UNLOCKED is displayed in the lower-left corner of the graticule area. This can occur when any of the following conditions exist:
—NO reference signal is present.
—A low or very high-level external reference signal is present. For best results, the signal should be between –5 dBm and +5 dBm.
—The external reference is off-frequency.
To learn the expected measurement accuracy when connected to a frequency reference source, see the FieldFox specifications in Appendix B: “Specifications/Data Sheet”.
Reference OUT
The internal 10 MHz frequency reference is available from the Ref/Trig output connector on the right-side panel. Use this signal as a common frequency reference when making measurements using external equipment. See this connector in “Top Panel” on page 47.
Variable Voltage Source (Opt. 309)
An internal DC source, available with Opt. 309, may be used to provide power for external devices. The maximum power available is 8 watts.
The voltage is output through an SMB (m) output connector located on the left-side panel. See the connector in “Left Side Panel” on page 50.
An optional SMB (f) to BNC (m) bias-tee power cable is available with Keysight part number: N9910X-713.
