Figure 6-13. Wave Generator Verification Setup
For wave generation verification procedures, refer to Figure 6-13 for the proper setup
connections.
Set the Calibrator Mainframe to SCOPE mode, with the Wavegen menu on the display.
Press O on the Calibrator Mainframe to activate the output. Set the offset to 0 mV,
and the frequency to 1 kHz. Then follow these steps to verify the wave generator
function.
6-67. Verification at 1 M Ω
Set the Calibrator Mainframe impedance to 1 MΩ (The blue softkey under SCOPE Z
toggles the impedance between 50 Ω and 1 MΩ).
1. Connect the BNC cable to the Calibrator Mainframe’s SCOPE connector. Connect
the other end of the BNC cable to the 5790A INPUT 2 using the BNC(f) to Double
Banana adapter.
2. Set the 5790A to AUTORANGE, digital filter mode to FAST, restart fine, and Hi
Res on.
3. Program the Calibrator Mainframe to output the wave type and voltage listed in
Table 6-41.
4. Allow the 5790A reading to stabilize, then record the 5790A rms reading for each
wave type and voltage in Table 6-41.
