FREQuency Subsystem
FREQuency commands configure the instrument's output frequency.
[SOURce:]FREQuency[:CW] <value>|MINimum|MAXimum[,<lower_limit>,<upper_limit>]
[SOURce:]FREQuency[:CW]? [MINimum|MAXimum]
[SOURce:]FREQuency[:IMMediate] <value>|MINimum|MAXimum[,<lower_limit>,<upper_
limit>]
[SOURce:]FREQuency[:IMMediate]? [MINimum|MAXimum]
Sets the immediate AC frequency and optionally the frequency soft limits.
Parameter Typical Return
40.0 to 500.0 Hz +5.00000E+01
Set the output frequency to 50 Hz: FREQ 50
This command takes one or three arguments. You cannot have a low or high limit without the other.
This command applies to AC, AC+DC, EXT-DC, and EXT-AC.
The *RST default is 60 Hz.
You should set this value between the lower and upper frequency soft limits.
Frequency suffixes (HZ and KHZ) are allowed.
[SOURce:]FREQuency:LIMit:LOWer <value>|MINimum|MAXimum
[SOURce:]FREQuency:LIMit:LOWer? [MINimum|MAXimum]
[SOURce:]FREQuency:LIMit:UPPer <value>|MINimum|MAXimum
[SOURce:]FREQuency:LIMit:UPPer? [MINimum|MAXimum]
Sets the lower or upper AC frequency soft limit.
Parameter Typical Return
40.0 to 500.0 Hz
Default 500 (UPPer) and 40 (LOWer)
+1.25000E+02
Set the frequency limits to 125 and 300 Hz:
FREQ:LIM:LOW 125
FREQ:LIM:UPP 300
FREQ:LIM:STAT ON
This command applies to AC, AC+DC, EXT-DC, and EXT-AC.
