20
Global IEXC Query: 1:0: IEXC?
Global IEXC Response: 1:IEXC:1=4;
OFLT
The OFLT command enables or disables the Output Filter.
The Output Filter value is sent as an integer value of either 0 -Disable or 1-Enable.
Setting:
2:1:OFLT= 1\r\n ( unit 2, channel 1, Output Filter Enabled )
Setting Response: 2: OFLT:ok
Query:
The FLTR query returns the channels Output Filter.
Query Format: Unit#:Ch#:CMD?
Response format: Unit#:Cmd:Ch#:= <0|1>;
Query: 2:1: OFLT?
Response: 2: OFLT:1=1;
Global OFLT Query: 1:0: OFLT?
Global OFLT Response: 1: OFLT:1=1;2=0;3=0;4=0;
OSCL
The OSCL command selects the Internal Reference Oscillator setting. When either the 100 or 1k Hz setting is
selected the channel is forced into a charge mode, if it isn’t set that way already, and an internal 100pC signal is
generated. This signal is then converted to a voltage based on the selected charge sensitivity (1mV/pC if any
ICP setting was selected) after which the channels gain is applied to provide an internal cal signal.
This feature is only available in units with an Isolation module.
The OSCL value is sent as an integer value of either 0 –Disable, 1-1000 Hz Enable, 2-100 Hz Enable
Setting:
1:1: OSCL= 1\r\n
( unit 1, channel 1, Oscillator=1 kHz )
Setting Response: 1:OSCL:ok
Query:
The OSCL query returns the channels Internal Reference Oscillator setting.
Query Format: Unit#:Ch#:CMD?
Response format: Unit#:Cmd:Ch#:= <0|1>;
Query: 1:1: OSCL?
Response: 1: OSCL:1=0;
Global OFLT Query: 1:0:OSCL?
Global OFLT Response: 1:OSCL:1=1;2=0;3=0;4=0;
