Push
. The Calibrator erases your entry from the Control Display and copies
it into the Output Display (below is typical).

15.
Push
to activate the Calibrator output. When you change the power output
levels, you must reenter voltage and current (in either order).
(Record voltage or current and then a watts entry value with
. The remaining
volts or current value is calculated and displayed.)

•
I OUT
selects AUX or 20A terminals. Current outputs 3 A or above are always on
the 20A terminals.
•
“LO”s
ties or opens a connection between front panel NORMAL LO and AUX LO
terminals. The front panel NORMAL LO and AUX LO terminals must be tied
together at the UUT or at the Calibrator. The default is tied.
Set AC Power Output
Note
Tie the terminals NORMAL LO and AUX LO together at the UUT, or at the
Calibrator with the “LO”s softkey selection “tied.” For optimum phase
performance, tie the LO terminals at the UUT. At current levels >2.2 A, tie
the terminals at the UUT. Use heavy gauge wire >10 m
Ω
resistance.
The Calibrator makes an ac power output by sourcing an ac voltage on the NORMAL
outputs and an ac current on the AUX outputs.
See “Set AC Voltage Output” in this chapter for information about ac voltage output in
dBm. This procedure that the ac voltage output is in volts.
Complete the subsequent procedure to set an ac power output. If you make an entry error,
push
one or more times to clear the display, then reenter the value.
Caution
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 erase output from the Calibrator.
2.
Connect the UUT as in the “Connect the Calibrator to a UUT” section of this chapter.
(Change the voltage and current connections to suit your application.)
3.
Set the UUT to measure ac power on the necessary range.
4.
Push the numeric keys and decimal point key to record the necessary voltage output
(maximum six numeric keys). For example, 123.456.
