Set AC Voltage Output

You can select an ac voltage output in volts or as a power output in dBm, where dBm is
10 log (Pout/.001), where Pout is shown in watts. The output range is 1 mV to 1000 V.
When you select dBm outputs, the Calibrator calculates dBm at a selected impedance
level. For this instance, the formula is:
Do this procedure to set an ac voltage output at the front panel NORMAL terminals. If
you make an entry error, push  to erase the display, then record the value again.
To prevent damage to the UUT, makes sure the applied voltage to
the UUT is not larger than the rating of the UUT insulation and the
connection wires.
1. Push  to clear output from the Calibrator.
1. Connect the UUT as in the "Connect the Calibrator to a UUT" section of this chapter.
2. Set the UUT to measure ac voltage on the necessary range.

A softkey name for range is shown on the Control Display in the dc voltage function:
Range (Operating Range) selects autorange (auto) or lock (locked) for the current
range. When auto (the default) is selected, the Calibrator automatically selects the
range that gives the best output resolution. When locked is selected, the Calibrator
will not change ranges when you edit the output. The locked selection is typically
made to prevent range changes that can cause a small agitation in the output, for
example, when you measure the linearity of a given multimeter range.
20 log(V) - 10 log(Impedance * .001) = dBm.
Output in volts:
Push the numeric keys and decimal point key to record the necessary voltage
output (maximum six numeric keys). For example, 2.44949.
