SYSTem:MODule:TEMPerature?
Syntax
SYSTem:MODule:TEMPerature? [<mode>], <slot>
Description
Operating the 34937A, 34938A and 34939A General-Purpose Switch Modules at their maximum rated current on all channels can cause them to overheat. A temperature transducer has been implemented on these modules to alert you to pending over-temperature conditions. This command reads the present temperature on the temperature transducer ("TRANsducer") or the factory-set temperature threshold ("TTHReshold") for the module in the specified slot.
|
|
No relays will be automatically opened as a result of an over-temperature condition on these modules. If you are planning to use these modules at or near their operating limits, be sure to implement the necessary procedures in your programming application to address the event of an over-temperature condition. |
Used With:
34937A 32-Channel General-Purpose Switch
34938A 20-Channel 5A Switch
34939A 64-Channel 1A Switch

Remarks
This command applies only to those modules listed above. An error will be generated if you send this command to a slot that doesn't contain one of these modules.
The factory-set temperature threshold for these modules is 70
°C (the threshold cannot be modified). You can configure the modules to generate a Service Request (SRQ) when an over-temperature condition exists. One over-temperature SRQ event is logged each time the temperature threshold is exceeded. See Agilent 34937A Event Registers or Agilent 34938A Event Registers for more information on configuring the Status Registers for these modules.
The front-panel "HOT" annunciator turns on when an over-temperature condition exists on one or more modules in the mainframe. The annunciator will remain on until the module temperature drops below the threshold.
Return Format
The command returns the present temperature on the temperature
transducer ("TRANsducer") or the factory-set temperature threshold
("TTHReshold") on the module in the specified slot. The value
is returned in
Examples
The following command reads the present temperature
on the module in slot 2. The transducer temperature is returned in

Typical Response: +3.65640000E+01
The following command reads the factory-set temperature
threshold (always 70
SYST:MOD:TEMP? TTHR,2
Typical Response: +7.00000000E+01
