Using Handler Interface

Control/Check the Handler Interface for Maintenance

When the drive source voltage is between 5 V - 9 V, the switch S1 is ON
(closed) and current flows through the input signal resistor of 1 kΩ.
When the source voltage is between 9 V - 15 V, the switch S2 is ON (closed)
and current flows through the input signal resistor of 2.27 kΩ.
When the drive source voltage is between 15 V - 24 V, the switch S3 is ON
(closed) and current flows through the input signal resistor of 3.68 kΩ.
If the source voltage exceeds the available range, the analog circuit in the
hardware might be damaged.
Control/Check the Handler Interface for Maintenance
To control/check the Handler interface, the Keysight E4981A provides several
test commands related to various operations of handler interface. This section
explains the various test commands available in E4981A to check/trouble the
handler interface.

Starting Handler interface test

Handler interface can be set into test mode by using the :TEST:HANDler:MODE
command. When this command value is set to ON, the handler interface pin
signal value can be controlled/read by :TEST:HAND:xxxx commands.

Using Handler interface test commands

After setting the :TEST:HANDler:MODE command value to ON, the following
commands can be used to control/read the handler interface pin signal value:

:TEST:HANDler:BIN sets the Handler Bin No.
:TEST:HANDler:COMP sets the Handler Comparator Function value.
:TEST:HANDler:KEYLock? gets the Handler/Key_Lock signal level as
HIGH/LOW.
:TEST:HANDler:STATus:ALARm sets the Handler Alarm signal to
HIGH/LOW.
:TEST:HANDler:STATus:EOM sets the Handler End of Measurement (EOM)
status to HIGH/LOW.
:TEST:HANDler:STATus:INDex sets the Handler Index value to HIGH/LOW.
:TEST:HANDler:STATus:NC sets the Handler No Contact/Low C Reject
signal to HIGH/LOW.
:TEST:HANDler:STATus:OVLD sets the Handler Overload signal status to
HIGH/LOW.
