RF Multiplexer Module

Using This Chapter

This chapter provides examples to switch multiplexer channels and to scan multiplexer channels. As required see Chapter 4, Understanding the RF Multiplexers, to modify the examples for your application. Also, see Chapter 5, RF Multiplexers Command Reference, for command information.

Multiplexer Commands

Table 3-1. RF Multiplexer Commands Used in Chapter 3

Command	Description

CLOS <channel_list>	Close channels
OPEN <channel_list>	Open channels

TRIG:SOUR BUS EXT HOLD IMM	Set scanning trigger source
SCAN <channel_list>	Define channels to be scanned
INIT	Start scan, close first channel

Switching Channels

∙Switching channels consists of closing or opening a channel. Close channels 00-03 by connecting a channel to com 00 or close channels 10-13 by connecting a channel to com 10. Only one channel per bank can be closed at a time.

∙ Use CLOSe <channel_list> to close channels use

OPEN <channel_list> to open channels. channel_list has the form (@ccnn) for a single channel, (@ccnn,ccnn,...) for two or more channels, or (@ccnn:ccnn) for a set of channels where cc = card number, nn = channel number.

∙Switching configurations include standard, matrix, and tree. See Chapter 2 for configuration details.
