Chroma 6404 - Page 43

Remote Operation
6-7
Return Parameters: <NR2>
Query Example: MEAS:POW:AC:PFAC? returns the output power factor.
MEASure:VOLTage:AC?
FETCh:VOLTage:AC?
Description: These queries return the output ac rms voltage.
Query Syntax: MEASure[:SCALar]:VOLTage:AC?
FETCh[:SCALar]:VOLTage:AC?
Parameters: None
Return Parameters: <NR2>
Query Example: MEAS:VOLT:AC? returns the output ac rms voltage.
OUTPut
Description: This command enables or disables the ac source output.
Syntax: OUTPut[:STATe] <Boolean>
Parameters: 0 | 1 | OFF | ON
*RST Value: OFF
Example: OUTP ON enables output
OUTP 0 disables output
Query Syntax: OUTPut[:STATe]?
Return Parameters: 0 | 1
Query Example: OUTP? returns the output enable condition.
OUTPut:PROTection:CLEar
Description: This command clears the latch that disables the output when a short, over
load, over power, over temperature, fan fail, under voltage condition is
detected. All conditions that cause the protection should be removed before
the latch can be cleared. The output then remains disabled until another
OUTP ON command is received.
Syntax: OUTPut:PROTection:CLEar
Parameters: None
Example: OUTP:PROT:CLE clears the latched protection.
CURRent:PEAK
Description: This command sets the output peak current.
Syntax: [SOURce:]CURRent:PEAK[:IMMediate] <NRf+>
Parameters: 0 to 10 for 6404, 0 to 20 for 6408
*RST Value: 10 for 6404, 20 for 6408
Example: CURR:PEAK 15 sets the output peak current to 15A.
CURR:PEAK MAX sets the output peak current to maximum value.
Query Syntax: [SOURce:]CURRent:PEAK?
Return Parameters: <NR2>
Query Example: CURR:PEAK? returns the setting value of output peak current.
FREQuency
Description: This command sets the output frequency.
Syntax: [SOURce:]FREQuency[:CW|:FIXed] <NRf+>
Parameters: 45 to 500
*RST Value: 60 Hz
Example: FREQ 120 sets the output frequency to 120Hz.
REQ MAX sets the output frequency to 500Hz.
Query Syntax: [SOURce:]FREQuency[:CW|:FIXed]?
Return Parameters: <NR2>
Query Example: FREQ? returns the setting value of output frequency.
