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).
nn075f.eps
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.
