4. Push the numeric keys and decimal point key to record the necessary frequency
output (maximum five numeric keys). Push a multiplier key, if necessary. For
example, push the kilo multiplier key

. Then push the

key. For example,
1.1234 kHz (see below).

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

6. Push

to start the Calibrator output.
Software names are shown on the Control Display in the ac voltage function, in
reference to which waveform is selected: DUTY, OFFSET and WAVE.

•
DUTY (Duty Cycle) When the square wave is selected, DUTY shows and lets you
change the duty cycle of the square wave. The range is 1.00 % to 99.00 %. The
default is 50.00 %. The duty cycle must be 50.00 % if it is necessary to record an
OFFSET (see below).
•
OFFSET (Voltage Offset) shows when the necessary output is less than 33 V (sine
waves), 65 V (square waves) or 93 V (triangle waves and truncated sine waves). This
softkey lets you to add a positive or negative dc offset voltage to the ac output signal.
See “Record a DC Offset” in this chapter for more information. When a voltage
output is shown in dBm, voltage offset is not available. You can record an offset for
a square wave output only when the duty cycle is 50.00 % (see DUTY above).
•
WAVE (Waveform) lets you select one of four different types of waveforms: sine
wave, triangle wave, square wave, and truncated sine wave. (See “Waveform Types”
in this chapter). When a non-sinusoidal waveform is selected, the Output Display
shows Pp (p-p). Output in dBm is sine wave only.
