Typical The multiplexer relays are configured in a “ tree” structure which provides high isolation and low VSWR (voltage standing wave ratio). Each channel Configuration can switch user inputs up to 42 Vdc or 42 Vac peak. User input frequencies to the multiplexers can be from dc to 1.3 GHz. The multiplexers can be configured for several arrangements, such as standard, tree, or matrix. You can use single scanning, multiple scanning, or continuous scanning for any configuration. For a SCPI (S

Multiplexer Card The multiplexer card number depends on the switchbox configuration (single-module or multiple-module) set for the multiplexers. (Leading Numbers zeroes can be ignored for the card number.) For a single-module switchbox, the card number is always 01. For a multiple-module switchbox, the card numbers are 01, 02,...,n. The switch module with the lowest logical address is always card number 01. The card number with the next successive logical address is card number 02, and so on

Use commas (,) to form a channel list or use a colon (:) to form a channel range. Only valid channels can be accessed in a channel list or channel range. Also, the channel list or channel range must be from a lower channel number to a higher channel number. For example, SCAN (@100:213) is acceptable, but SCAN (@213:100) generates an error. Example: RF Multiplexer Channel Lists/Ranges Channel Lists: CLOS (@100,112) !Close channels 00 and 12 on card 01 OPEN (@203,210) !Open channels 03 and

Caution CENTER CONDUCTOR MAY SHORT TO SHIELD. Each channel’s center conductor may momentarily short to the shield when the channel is opened or closed. Use only resistive (50Ω or 75Ω) or current-limited (<1 A) inputs with less than 0.1 μF total capacitance. Caution STATIC-SENSITIVE DEVICE. Use anti-static procedures when removing, configuring, and installing a module. The multiplexer modules are susceptible to static discharges. Do not install a multiplexer without its metal shield attached

Some guidelines for user input cabling are: • For best high-frequency performance, user cabling should have at least two braided shields or one braid and a foil wrap. • Always use shielded coaxial cables with the characteristic impedance of the multiplexer used (50Ω or 75Ω). Keep cables as short as possible, especially in high-frequency circuits or pulse circuits where a rise/fall time of <50 nsec is critical. • Long cables can add delay time which can cause timing problems. All test equipment,

Typical Multiplexer Configurations Typical RF multiplexer configurations are: • Standard configuration (2 x 4:1 multiplexer) • Tree configuration (1 x 12:1 multiplexer) • Matrix-type configuration (4:1 to 4:1 multiplexer) Standard Figure 2-2 shows the standard configuration (2 x 4:1) for the RF multiplexers. With this configuration, you can switch channels 00-03 to Configuration com 00 and switch channels 10-13 to com 10. One channel per bank can be connected to its common at a time. Figure 2
