Keithley 3720-ST User Manual

Section 11: TSP command reference Series 3700A System Switch/Multimeter Reference Manual

If channels are specified, the count values are returned in the order in which the channels are
specified. If slots are specified, the response lists the channels starting from lowest to highest.
Because each slot is processed completely before going to the next, all slot 1 channels and analog
backplane relays are listed before slot 2 channels.
Relay closures are counted only when a relay cycles from open to closed state.
It is good practice to get the relay count at the end of a program. This saves the latest count to
memory.
An error is generated if:
• A specified channel is invalid
• The channel does not have a count closure associated with it
Example 1
counts = channel.getcount("2001:2005")
print(counts)
Gets the close counts for channels 1 to 5 on
slot 2.
Example output for channels 2001, 2002,
2003, 2004, and 2005:
672,495,547,479,518
Example 2
counts = channel.getcount("slot2")
print(counts)
Get the close counts for all channels and
analog backplane relays on slot 2 assuming
a 3721 card is installed in the slot.
Sample output that shows the counts for
channels 1 to 41, analog backplane relays
911 to 917, analog backplane relays 921 to
928:
672,495,547,479,518,459,522,599,4
52,451,464,427,426,428,426,425
,428,424,424,425,5,3,3,3,4,3,3
,5,3,33,33,33,33,33,33,32,32,3
2,32,32,119,3,56,0,0,0,0,0,0,1
4,68,0,0,0,0,16,0
Example 3
channel.pattern.setimage("2003, 2005, 2023, 2915", "Path")
PathList = channel.pattern.getimage("Path")
print(PathList)
print(channel.getcount(PathList))
print(channel.getcount("Path"))
Create a pattern called Path, then get the close counts for channels and analog backplane relays in channel
pattern called "Path"
Sample output:
2003, 2005,2023,2915
547,518,3,0
547,518,3,0
