Model 6517B Electrometer Reference Manual Section 14: SCPI command reference

6517B-901-01 Rev. C / August 2015 14-43

:PASS:SOURce <NRf>

This command specifies the digital pattern for the output port.

Usage

:CALCulate3:PASS:SOURce <NRf>

:SOURce?

<NRf>

 0 to 15: Specify digital pattern for output port

Details

Description This command is used to specify which line(s) of the Digital Output Port goes true when

there are no failures in the limit tests. Each output line is assigned a decimal weight as follows:

Digital Output Decimal Weight

Line #1 1

Line #2 2

Line #3 4

Line #4 8

The parameter value for the digital pattern is determined by adding the decimal weights of the desired

output lines. For example, if you want output lines #2 and #3 to go true when all enabled limit tests

pass, use a parameter value of 6 (2+4).

The actual true state (high or low) of each digital output line depends on its programmed polarity.

Polarity is programmed from the OUTPut Subsystem.

Note that when the binning strobe is enabled, output line #4 is not considered to be part of the digital

output pattern. The binning strobe uses line #4. With the strobe enabled, parameter values 8 through

15 are treated the same as parameters 0 through 7.
