10 MHz Reference IN/OUT

10 MHz Reference Input When a 10 MHz external reference signal is detected at this port, it will be used as the instrument frequency reference instead of the internal frequency reference.

10 MHz Reference Output This BNC(f) connector outputs a frequency reference signal for use by other test equipment.

Press Setup > Internal Hardware > Reference... to switch external/internal reference.
From SCPI, use SENS:ROSC:SOUR

SRC3 Connector

Provides a synthesizer output from 10 MHz to 13.5 GHz (Option XSB) and also requires Option 422 or 423.

GPIB Controller and Talker/Listener Ports

The PNA-X can be a GPIB Controller and Talker/Listener. Learn more.

PCIe X4 Connector (CPU 8.0, 7.0)

The PCIe X4 connector is a 4-lane slot for future enhancements.

USB Hub

This USB hub contains two SuperSpeed USB ports to power your VNA peripherals. There is also one USB port below the LAN connector, one USB device port, and four USB ports on the front panel.

Limitation: The total current limit for all rear panel USB ports is 2.3 amps. The total current limit for all front panel USB ports is 2 amps. When first connected, Keysight ECal modules 8509x and N4431 draw significantly more current than other modules. See Specifications.

PNA with CPU Version 9.0

This USB hub contains four SuperSpeed USB ports to power your VNA peripherals. There is also one USB device port, and four USB ports on the front panel. The CPU 9.0 provides a total current limit on the four USB-3.0 ports of 3.6 amps.

See Important First-time USB connection note.

Display Port (CPU 9.0)

The Display Port is used to connect to external displays and replaces the VGA connector.

RF Path Access

These connectors are NOT available on the N522x and N5264B models.

These connectors allow RF Path Configuration.

Ports 3 and 4 are not available on 2-port models.

N5247A - J8 thru J11 are moved to the front-panel.

RF and LO OUT

The RF OUT connector is NOT available on the N5264B

For the N5247B and N5227B:- Added RF2 OUT (J12) for 4-port 110 GHz single sweep VNA. Enables driving two mmWave modules simultaneously. Learn more.

Caution: LO OUT has more power than previous VNA models.

See specifications

IF Path Inputs

Option 020 adds these connectors, which allow access to the VNA Receiver / IF paths.

These are labeled A, B, C/R1, D/R2, R.

For 2-port models, use A, B, R1, R2.
For 4-port models, use A, B, C, D, R.

See IF Path Configuration settings and block diagram.

Power I/O

See Details

+28 VDC (BNC output)

Used to power a noise source for the Noise Figure App.

Maximum steady-state current = 300 mA.
Maximum in-rush current = 500 mA.
This output is protected with a self-healing fuse.

External and AUX Trigger I/O

MEAS TRIG IN - When enabled, VNA is triggered by signals on this connector. Learn more.

MEAS TRIG RDY When enabled, VNA outputs a 'READY' signal on this connector to other devices. Learn more.

AUX TRIG 1&2 IN When enabled, VNA accepts signals on these connectors which indicates that the external devices are ready to be triggered. Learn more.

AUX TRIG 1&2 OUT When enabled, VNA outputs signals on these connectors either before or after a measurement. Learn more.

Test Set I/O

See Details

Bias IN and Fuses

Connect your DC Power Supply to apply Bias to the VNA ports through these BNC connectors.

The bias fuses are rated for 0.5A. You are responsible to ensure that devices connected to the test port do NOT draw more current than 0.5A. This will occur, for example, if a calibration SHORT is connected to the test port with bias power ON. The fuse Keysight part number for the PNA-X is 2110-0824.
The VNA will meet all of its RF specifications with bias up to 200 ma. As the DC bias is increased, corrected source match and directivity will degrade at low RF frequencies.
