Command Syntax
[SOURce:]VOLTage[:AC]:LIMit:MAXimum
Description
Sets high user limit for AC voltage programming. User limits must fall
within actual hardware limits of the power source. Also, MAX limit
must be greater than MIN limit.
Parameters
0.000 – 300.000
Parameter Format
<nr2>
Example
VOLT:LIM:MAX 240.0

Query Format
[SOURce:]VOLTage[:AC]#:LIMit:RANGe?
Description
Returns available AC voltage range low and high limits.
Returned Data Format

Query Example
VOLT:AC1:LIM:RANG?
0.0000,300.0000
Query Format
[SOURce:]VOLTage[:AC]#:LIMIT:SATuration:RANGe?
Description
Returns the upper and lower limit sine wave RMS voltage at which
saturation of the output inverter will occur. Saturation limits are
determined in the maximum peak voltage capability of the AC+DC
components at the output of the power source. For the AFX Series®,
these limits are -425 and +425V. The VOLT:AC1:LIM:SAT:RANG?
returns the min and max. RMS of a sine wave that may be
programmed based on the programmed DC component.
Maximum allowable values are:
Maximum positive peak voltage:
V_peak_max = V_AC_pe V_DC
Minimum negative peak voltage:
V_peak_min = V_AC_pe V_DC
For a sinusoidal AC waveform, these limits are:
Vrms_sat = (
425
– Vdc) / 1.4142
Vrms_sat = (
-425
+ Vdc) / 1.4142
Examples
V_DC = 0
425 = 1.41 *
300
+ 0 (
V_AC_rms_sat = 300
)
V_DC = 100
425 = 1.41 *
229
+ 100 (
V_AC_rms_sat = 229
)
V_DC = 425
425 = 1.41 *
0
+ 425 (
V_AC_rms_sat = 0
)
