CALCulate:COMPare:TYPE

Syntax CALCulate:COMPare:TYPE <mode>[,(@<ch_list>)]

CALCulate:COMPare:TYPE? [(@<ch_list>)]

Description This command sets the pattern comparison mode for the specified digital input channels.

The instrument will generate an alarm when the digital input value is the same as or

different from the pattern defined.

Channel

List

One or more channels (only for the DIO

channels), the rules are as follows:

(@101): channel 01 on the module in

Slot1;

(@101:103): channel 01 through 03 on

the module in Slot1;

(@101:103,301): channel 01 through 03

on the module in Slot1 and channel 01 on

the module in Slot3.

If the parameter

is omitted, this

command will

be applied to the

whole scan list.

Explanation  This command is only valid for the DIO channels of MC3534 (multifunction module).

The specified DIO channels do not have to be part of the scan list.

 In pattern comparison, the bits of which the mask value (set using the

CALCulate:COMPare:MASK command) are 0 will be ignored and only the bits of which

the mask value is 1 will be compared. When EQUal is selected, the instrument

generates an alarm when the input pattern monitored is the same with the alarm

value (set using the

CALCulate:COMPare:DATA command). When NEQual is selected,

the instrument generates an alarm when the input pattern monitored is different from

the alarm value.

 A Factory Reset (the

*RST command) clears the pattern compare setting and turns

off the pattern comparison mode. An Instrument Preset (the

SYSTem:PRESet

command) or Card Reset (the

SYSTem:CPON command) does not clear the pattern

compare setting and does not turn off the pattern comparison mode.

Return

Format

The query returns EQU or NEQ. Multiple return values are separated by commas.

Example

CALC:COMP:TYPE EQU,(@301:304)

CALC:COMP:TYPE? (@301:304)

The query returns EQU,EQU,EQU,EQU.
