Scanning Channels Commands

Scanning RF multiplexer channels consists of closing a set of channels, one at a time. Single scan, multiple (2 to 32767) scans, or continuous scanning modes are available. See Figure 4-1 for scanning commands.

Using Scanning Trigger Sources

The TRIG:SOUR command specifies the source to advance the scan. You can use the TRIG command to advance the scan when TRIG:SOUR BUS or TRIG:SOUR HOLD is set. The OUTP command can be used to enable the HP E1300A/E1301A Trig Out or the HP E1405A/E1406A port. Figure 4-2 shows scanning trigger sources.

Scanning with External Instruments

Scanning RF multiplexer channels has the same effect as executing multiple CLOSe commands. Thus, scanning is useful when the outputs7from a number of DUTs are to be measured with an instrument. Two examples using HP BASIC programming language follow.
