1. Press R to clear any output from the 5520A.
2. Connect the UUT as described earlier in this chapter under “Connecting the
Calibrator to a UUT.”
3. Set the UUT to measure ac voltage on the desired range.
4. Output in volts Press the numeric keys and decimal point key to enter the desired
voltage output (maximum six numeric keys). For example, 2.44949.
Output in dBm Press the numeric keys and decimal point key to enter the desired
power output (maximum six numeric keys). For example, 10.0000. For a power
output less than 1 mW (negative dBm values), press I to append the numeric
entry with the negative (−) symbol.
When you press the dBm key, the right most softkey becomes active. This allows the
dBm value and output impedance to be entered as a unit.
When output is entered in dBm, the Control Display appears as follows:
