(Waveform command) Sets the waveforms for ac outputs. If the Calibrator is sourcing
one output, one parameter is required. If the Calibrator is sourcing two outputs, two
parameters are required or one parameter to set the waveform to both outputs. Waveform
choices are SINE (sine wave), TRI (triangle wave), SQUARE (square wave), TRUNCS
(truncated sine wave), or NONE (waveform does not apply).
Parameter: <1st waveform> , (SINE, TRI, SQUARE, TRUNCS, NONE)
<2nd waveform> (SINE, TRI, SQUARE, TRUNCS, NONE)
Example: WAVE SINE,SQUARE
Set the waveforms for a dual output to Sine wave on the primary output (Calibrator front
panel NORMAL terminals) and Square wave on the secondary output (front panel AUX
or 20A terminals).

(Waveform query) Returns the waveform types for ac outputs. Waveform choices are
SINE (sine wave), TRI (triangle wave), SQUARE (square wave), TRUNCS (truncated
sine wave), or NONE (waveform does not apply).
Responses: <1st waveform> , (SINE, TRI, SQUARE, TRUNCS, NONE)
<2nd waveform> (SINE, TRI, SQUARE, TRUNCS, NONE)
Example: WAVE? returns SQUARE,NONE
Returns SQUARE when the ac primary output (Calibrator front panel NORMAL
terminals) is a square wave and NONE when there is no secondary output on the front
panel AUX terminals.

(Impedance Compensation command) Activates or deactivates 2-wire or 4-wire
impedance compensation. For resistance output, compensation is allowed when the
resistance is less than 110 kΩ. For capacitance output, compensation is allowed when the
capacitance is equal to or greater than 110 nF. For all other resistances and capacitances,
the compensation is NONE and attempts to use other parameters results in the error
message “Can’t change compensation now.” For RTD temperature simulation,
compensation is allowed for all temperatures.
Parameter: NONE (Turns off impedance compensation circuitry)
WIRE2 (Turns on the 2-wire impedance compensation circuitry)
WIRE4 (Turns on the 4-wire impedance compensation circuitry)
Example: ZCOMP WIRE2
Set 2-wire impedance compensation for the Calibrator UUT connection. (Resistance if
the ohms value is less than 110 kΩ, capacitance if the farads value is 110 nF or more, or
RTD temperature simulation, any value.)

(Impedance Compensation query) Returns status of 2-wire or 4-wire impedance
compensation.
Responses: NONE (impedance compensation is turns off)
WIRE2 (2-wire impedance compensation is on)
WIRE4 (4-wire impedance compensation is off)
