Gain Verification Test

The gain verification tests check the positive and negative full scale gain on each range for each channel. An external DCV source provides the input and the digitizer’s "L" terminal is connected to the "G" terminal connecting LO to GUARD. The input voltage is slightly less than full scale to avoid overloading the range.

1 Set the digitizer as follows:

Reset the digitizer: *RST (sets FILT OFF)

Set channel 1 to the 62 mV range: VOLT1:RANG 62E-3

2 Set the DC Standard output to 55 mV.

3Perform the measurement using the INITiate command. Retrieve the reading using DATA? 1,(@1).

4 Verify the result is within specified limits and record the result.

5Change ranges using VOLT<channel>:RANG <range> and make a measurement for each DCV input and range shown in Table D-4, verifying the result is within specified limits. Record the result.

6Repeat step 5 for channel 2 on the E1563A 2-Channel Digitizer and channels 2 through 4 on the E1564A 4-Channel Digitizer.
