Filter Bandwidth Verification Test

This test checks the filter input bandwidth for the 25 kHz filter on the E1563A or each of the four filters (1.5 kHz, 6 kHz, 25 kHz and 100 kHz) on the E1564A. The test This test uses an external source connected to the HI and LO Input terminals and has the "L" terminal connected to the "G" terminal. The digitizer is set to the 1V range for all tests.

1Set the digitizer as follows: Reset the digitizer: RST

Set all channels to 1V range: VOLT1:RANG 1; VOLT2:RANG 1; etc.

Set input filter frequency to 25 kHz: INPut1:FILTer:FREQ 25e3; INPut2:FILTer:FREQ 25e3

Enable the input filter: INPut1:FILTer:STATe ON; INPut2:FILTer: STATe ON

2Set the AC Standard output to 0.95V @ 25 kHz and connect the standard to the digitizer’s channel 1.

3Perform the filter bandwidth measurement using INITiate. Retrieve the reading using DATA? 1,(@1). Record the result on the Performance Test Record and verify the result is within specified limits.

4.Move the AC Standard output to the channel 2 input. Perform the filter bandwidth measurement using INITiate. Retrieve the reading using DATA? 1,(@2). Verify the result is within specified limits and record the result.

5Repeat Steps 2 through 4 for channels 3 and 4 on the E1564A

4-Channel Digitizer using: VOLT3:RANG 1, INPut3:FILTer: FREQ 25e3, INPut3:FILTer:STATe ON, VOLT4:RANG 1, INPut4:FILTer:FREQ 25e3, INPut4:FILTer: STATe ON.

6E1564A 4-Channel Digitizer: Test the remaining three filters present on the E1564A 4-Channel Digitizer. Repeat steps 2 through 5 for the remaining three input frequencies in Table D-5 for channels 3 and 4.

NOTE This requires you change input filters before you begin testing by executing the INPut<channel>:FILTer:FREQ <filter_frequency> command. Also, Step 3 requires DATA? 1,(@3) and Step 5 requires DATA? 1,(@4).
