Scanning Channels

Example: Scanning
Using Trig Out Port
Chapter 3
Scanning channels consists of closing a set of channels, one channel
at a time. You can scan any combination of channels for a
single-multiplexer or multiple-multiplexer switchbox.
Single, multiple, or continuous scanning modes are available. Any
switching configuration can be used for scanning. See Chapter 4.
This example shows one way to synchronize instrument measurements of DUTs
with RF multiplexer channel closures. For measurement synchronization, the HP
E1300A/E1301A Trig Out BNC port is connected to the instrument External
Trigger In port. See the following figure for typical user connections.
For this example, the mainframe and instrument are connected via HP-IB
with mainframe address of 709 and instrument address of 722. The RF
multiplexer is at logical address 120 (secondary address 15). (You must add
required instrument commands to line 10.)
10 OUTPUT 722;"TRIG EXT;...."
20 OUTPUT 70915;"OUTP ON"
30 OUTPUT 70915;"TRIG:SOUR BUS"
40 OUTPUT 70915;"SCAN (@100:103)" ! Scan channels
50 OUTPUT 70915;"INIT"
60 FOR I=1 TO 4
70 ENTER 722;A
80 PRINT A
90 TRIGGER 70915
100 NEXT I
110 END
