AC Voltage Output
To set an ac voltage output:
1. Make sure the Calibrator is in standby (STANDBY annunciator lit). Push  if
necessary.
2. If the UUT is not connected, connect it now as described in this chapter under
“Connect the Calibrator to a UUT.”
3. Set the UUT to measure ac voltage on the appropriate range.
4. Enter the necessary voltage output in volts or dBm with the numeric keypad.
Note
In the ac voltage function, dBm means decibels relative to 1 mW, calculated
for a 600
Ω load. The formula to calculate dBm is 10 log (power in mW).
For example, if 3.0V is supplied to a 600
Ω load, the dBm level is:
10 log (15.0 mW) = 11.7609 dBm.
If the Calibrator is switched to Wideband AC output, but dBm is kept as the
displayed units, the dBm value changes. The value changes because dBm is
calculated for a 50
Ω load in the Wideband AC output function. With the
use of the same voltage level as in the previous example, if the Calibrator is
switched to Wideband AC output, the dBm level changes to 10 log
(180.0 mW) = 22.5527 dBm.
5. To enter a negative dBm value, push .
6. Push , , or  if necessary.
7. Push  for volts, or push for a dBm level.
8. The display now shows the amplitude of the entry. If an entry error is made, push 
to clear the display, then reenter the value. If the most recent digit entered is in error,
push  to clear that digit. The display shown below assumes an entry of 19 V:
