像Ulf提到的那样,可以从前面板或使用TEMP远程查询3458A内部温度?
命令。
如果从前面板查询,则没有内部存储此值的方法。
或者,在开始测试之前执行ACAL(例如ACAL DCV,ACAL OHMS,ACAL AC,ACAL ALL)会在执行校准时在内部存储3458A的内部温度。
可以使用以下命令和校准常数ID来读取此温度:CAL?
175 - acal dcv temperatureCAL?
176 - acal ohm temperature CAL?
177 - acal acv temperature在测试完成后执行ACAL将在测试期结束时提供内部温度。

Like Ulf mentioned the 3458A internal temperature can be queried from the front panel or remotely using the TEMP? command. There is no method for storing this value internally if queried from the front panel.
Alternatively, performing an ACAL (e.g. ACAL DCV, ACAL OHMS, ACAL AC, ACAL ALL) prior to starting your tests does store the internal temperature of the 3458A internally at the time the calibration is performed. This temperature can be read using the following command and calibration constant id’s:
CAL? 175 – acal dcv temperature
CAL? 176 – acal ohm temperature
CAL? 177 – acal acv temperature
Performing an ACAL after the tests complete will provide the internal temperature at the end of the test period.
