Performance Verification
Check Offset Accuracy
Pulse Response Check
F-30
This procedure checks the output offset accuracy.
Electrical Characteristic Checked: Main Outputs, Offset, Accuracy, on
page E–3.
Equipment Required: A 50 W coaxial cable, 50 W termination, BNC-to-dual
banana adapter, and a digital multimeter (DMM).
Prerequisites: The instrument must meet the prerequisites listed on page F–3.
Procedure:
1. Use the test setup and test equipment settings from previous check.
2. To check offset accuracy:
a. Type:
IBWRTF Z1000.PAT <RETURN>
IBWRTF OFFSET1.CMD <RETURN>
b. Check that the DMM voltage reading is between +1.2325 V and
+1.2675 V.
c. Type:
IBWRTF OFFSET2.CMD <RETURN>
d. Check that the DMM voltage reading is between –1.2675 V and
–1.2325 V.
3. End procedure: Disconnect the DMM and the termination.
This procedure checks the pulse response characteristics of the VX4792 Arbi-
trary Waveform Generator output waveforms at amplitudes of 0.5 V and 1 V.
Electrical Characteristic Checked: Main Outputs, Pulse Response, on
page E–3.
Equipment Required: A 50 W coaxial cable and an oscilloscope.
Prerequisites: The instrument must meet the prerequisites listed on page F–3.
Procedure:
1. Install test setup and set test equipment controls (see Figure F–15):
a. Connect the oscilloscope: Connect the WAVEFORM OUTPUT
connector through the coaxial cable to the CH1 vertical input connector
on the oscilloscope.
