Rear Panel: Names and Functions of Parts

MY477/SG477 and above

MY466/SG466 and below

1. Handler I/O Port

The terminal to which an automatic machine (handler) used on a production line is connected. See Handler I/O Port.

Connector type: 36-pin Ribbon (Centronics) connector

2. Ethernet Port

A terminal for connecting the E5071C to a LAN (Local Area Network). Connecting this instrument to a LAN enables you to access the hard disk drive of this instrument from an external PC or to control this instrument by using SICL-LAN or telnet.

3. External Monitor Output Port/Display Port (Video)

A terminal to which an external color monitor (display device) can be connected.

[S/N prefix MY477/SG477 or above]

Connector type: Display Port and 15-pin VGA connector female.

By connecting a color monitor to this terminal, Keysight Technologies logo is shown on an external color monitor as the extended desktop.

When the same information shown on the LCD screen of the main body, Go to Windows -> Control Panel -> Appearance and Personalization -> Connect to an external display. Select “Duplicate these displays” at Multiple displays and then click Apply and OK.

[S/N prefix MY466/SG466 or below]

Connector type: 15-pin mini-D sub connector, Female.

By connecting a color monitor to this terminal, the same information shown on an external color monitor as the clone displays.

4. GPIB Connector

The connection of an external controller through General Purpose Interface Bus (GPIB) connector allows you to configure an automatic measurement system.  

This GPIB connector is used only for controlling the E5071C from an external controller. Use USB/GPIB interface to control other devices from the E5071C. You cannot control other devices from the E5071C through this GPIB connector.

5. External Trigger Input Port (Ext Trig)

A connector to which external trigger signals are input. This connector detects the downward transition from the HIGH state in TTL signals as the trigger signal. To use this connector to generate a trigger, you must set the trigger source to "external" (key operation: Trigger > Trigger Source >  External).

Connector type: BNC connector, female

6. Fan

The cooling fan for controlling the temperature inside the E5071C. This fan exhausts heated air from inside the analyzer to the outside.

7. Line Switch (Always ON)

Always keep this switch on (|).

• Do not use this switch to turn off (O) the mains. Doing so may cause the analyzer to fail. For more information, see the description of the Standby Switch.

8. Power Cable Receptacle (to LINE)

The receptacle (outlet) to which the power cable is connected.

• To connect the device to a power source (outlet), use the supplied three-prong power cable with a ground conductor. The plug attached to the power cable (on the power outlet side or device side of the cable) serves as the disconnecting device (device that cuts off power supply) of the E5071C. When the power supply must be cut off to avoid such danger as electric shock, pull out the power cable plug (on the power outlet side or device side of the cable). For the procedure for turning off the mains in normal use, see the description in Standby Switch.

For more on the power supply, see the Installation Guide.

9. High Stability Frequency Reference Output Port (Ref Oven, Option 1E5 only)

When Option 1E5 (high stability frequency reference) is installed, the reference signal is output from this connector.

• When Option 1E5 (high stability frequency reference) is installed, connect this connector to the External Reference Signal Input Connector (Ref In) by using the BNC(m)-BNC(m) cable included with the option.

10. External Reference Signal Input Port (Ref In)

The reference signal input connector for phase-locking the measurement signal from the E5071C to the external frequency reference signal. Inputting the reference signal to this connector improves the accuracy and frequency stability of the measurement signal from the E5071C.

• When the frequency reference signal is input to this connector, the measurement signal from the E5071C is automatically phase-locked to the reference signal. When an input signal is not present, the frequency reference signal inside the E5071C is automatically used. The ExtRef on the instrument status bar is displayed in blue when the system is phase-locked to the external reference signal and in gray when not phase-locked.
  
  When using Option 1E5 (high stability frequency reference), connect this connector to the High Stability Frequency Reference Output Connector (Ref Oven, Option 1E5 only) by using the BNC(m)-BNC(m) cable included with the option.

11. Internal Reference Signal Output Port (Ref Out)

A connector for outputting the internal frequency reference signal from the E5071C. By connecting this output connector to the external reference signal input connector of another device, the device can be phase-locked to the internal reference signal of the E5071C and used under this condition.

12. Serial Number Plate

The label showing the product number, serial number and the installed option number. The accessary and system rack options are not listed on this label. (CFGxxx or ATOxxx in the first line is for Keysight Use Only.)

13. Certificate of Authenticity Label

The label showing the information of the Certificate of Authenticity of Windows.

14. Rear USB Port

Four USB (Universal Serial Bus) ports are provided that can be used for connecting to  ECal (Electronic Calibration) module, USB, Multiport test set or a printer. Connecting a designated ECal module to this port enables ECal measurements to be taken. Connecting a compatible printer to this port enables screen information on the E5071C to be printed.

• The specifications of this port are identical to the Front USB Port.

15. USB (USBTMC) Interface Port

Through this port, you can control the E5071C from external controllers. For more information on the measurement system using the USB port, see the USB Remote Control System.

16. External Trigger Output Port

The External Trigger Output Port can output the pulse with the specified polarity either before or after the measurement of each point.

• The External Trigger Output Port can safely handle a maximum Output Current of 50mA.

17. Bias Input Ports

This BNC female connector allows external bias to be applied at the test ports.


 

• Do not apply DC voltage exceeding 35 Volt.

• Bias Input Port is an optional component of E5071C. Valid for options: 235, 435, 285, 485.

18. Fuse for Bias Input Ports

Fuse for Bias Input Ports is an optional component of E5071C. Valid for options: 235, 435, 285, 485.

19. Aux Input Ports

The Aux Input Ports are used to input DC signal for DC signal measurement.
