10-4-29. OUTPut? QUERY
Syntax:
Short Form: OUTP?
Long Form: OUTPut?
Description:
Indicates whether power supply output is enabled or disabled. Returns 0 if output disabled,
returns 1 if output enabled.
Return Format:
<Bool>
Example:
OUTP? returns 1 (the DC output of the power supply is enabled).
10-4-30. FETCh? QUERY
Syntax:
Short Form: FETC?
Long Form: FETCh?
Description:
Measures actual output voltage and current. The query performs a measurement and
returns the value of DC output current in Amperes and DC output voltage in Volts.
Return Format:
<NR1>
Example:
FETC? returns 1.01 , 3.00100E-00 (Voltage is 14.1V and current is 3.001A)
10-4-31. MEASure:VOLTage? QUERY
Syntax:
Short Form: MEAS:VOLT?
Long Form: MEASure:VOLTage?
Description:
Measure commands measure the output voltage.
Return Format:
Volts as a 5-
digit number, which is one decimal place more than the power supply’s
front panel voltmeter
Example:
Example : MEASure:VOLTage? Returns the output voltage value.
10-4-32. MEASure:CURRent? QUERY
Syntax:
Short Form: MEAS:CURR?
Long Form: MEASure:CURRent?
Description:
Measure commands measure the output current.
Return Format:
Amps as a 5-digit number, which is one decimal place more th
an the power supply’s
front panel ammeter
Example:
MEASure:CURRent? Returns the output current value.
10-4-33. MEASure:ADDRess? QUERY
Syntax:
Short Form: MEAS:ADDR?
Long Form: MEASure:ADDRess?
Description:
Query the address, the returned address will be different when using the different
interfaces.
Return Format:
address,Volt,curr
Example:
MEAS:ADDR?
When using RS-485, the power supply returns
A007,1.02,3.01,3.03
When using GPIB, the power supply returns
7,1.02,3.01,3.03
