Verification At 1 M; Verification At 50; Verification At - Fluke 5520A Service Manual

BNC (F) to
Double Banana Feed Through
Adapter Termination
Set the Calibrator Mainframe to SCOPE mode, with the Wavegen menu on the display.
Press 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.

6-134. Verification at 1 M

1. Set the Calibrator Mainframe impedance to 1 M (The blue softkey under SCOPE Z
toggles the impedance between 50
2. 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.
3. Set the 5790A to AUTORANGE, digital filter mode to FAST, restart fine, and Hi
Res on.
4. Program the Calibrator Mainframe to output the wave type and voltage listed in
Table 6-58.
5. Allow the 5790A reading to stabilize, then record the 5790A rms reading for each
wave type and voltage in Table 6-58.
6. Multiply the rms reading by the conversion factor listed to convert it to the peak-to-
peak value. Compare result to the tolerance column.

6-135. Verification at 50

1. Set the Calibrator Mainframe impedance to 50
toggles the impedance between 50
2. Connect the BNC cable to the Calibrator Mainframe's SCOPE connector. Connect
the other end of the BNC cable to the 50
5790A INPUT 2 using the BNC(f) to Double Banana adapter.
3. Set the 5790A to AUTORANGE, digital filter mode to FAST, restart fine, and Hi
Res on.
