    Mode specific parameter selections can vary based on the selected operating mode. Setup commands can be sent at any time. If the HVM100 is running, and changing the parameter requires a reset, then the setup command will cause the instrument to automati- cally stop, reset, change the parameter setting and start run- ning again.

    DC Output For all of the Analog AC and Analog DC outputs, the output impedance of the HVM100 is 475 ohms. For minimal error, connect to instruments with an input impedance of greater than 100,000 ohms when making AC or DC output measure- ments.

    20 dB). Therefore, in order for the HVM100’s AC output to function properly with each range (i.e. gain settings of 0, 20, 40, and 60 dB), the HVM100’s gain set- tings also affect the AC output signals. For example, with a gain setting of 0 dB, the HVM100 can measure input signals as large as 5.0 Vrms.
