Wideband Ac Voltage Output (Option 5700A-03) - Fluke Calibration 5730A Operator's Manual

Wideband AC Voltage Output (Option 5700A-03)

To set an output from the Wideband AC Module (Option 5700A-03), proceed from
or the power-up state as follows:
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 previously in this chapter
under "Connect the Calibrator to a UUT."
3. Set the UUT to read ac voltage on the appropriate range.
4. Touch Wideband.
5. With the numeric keypad, enter the necessary output amplitude, expressed as voltage
or a dBm level.
In the Wideband AC function, dBm means decibels relative to 1 mW,
calculated for a 50
in mW). For example, if 3.0 V is supplied to a 50
10 log (180.0 mW) = 22.5527 dBm
If the Calibrator is switched to standard ac output, but dBm is kept as the
displayed units, the dBm value changes. The value changes because dBm is
calculated for a 600
same voltage level as in the previous example, if the Calibrator is switched
to standard ac output, the dBm level changes to:
10 log (15.0 mW) = 11.7609 dBm.
6. To enter a negative dBm value, push .
7. Push  or  if necessary.
8. Push  for volts or  for volts expressed as dBm.
