Low Frequency Multiplexer Modules Operating Considerations Current Ratings See the Introduction to the Plug In Modules chapter of the 34980A Mainframe User’s Guide for detailed environmental operating conditions for the 34980A mainframe and its installed modules. That guidance sets maximum per channel current ratings at rated voltage for pollution degree 1 (dry) and pollution degree 2 (possible condensation) conditions, for all of the multiplexer modules. -
Page 13: Scpi Programming Examples For The Multiplexer Modules
Low Frequency Multiplexer Modules SCPI Programming Examples for the Multiplexer Modules SCPI Programming Examples for the Multiplexer Modules The programming examples below provide you with SCPI command examples to use for actions specific to the MUX modules. The slot and channel addressing scheme used in these examples follow the form sccc where s is the mainframe slot number (1 through 8) and ccc is the three-digit channel number. - Page 14 Low Frequency Multiplexer Modules Exampl - e - Closing and opening Analog Bus relays: The following command connects the Analog Buses to Bank 1 (via the Analog Bus relays on Bank 1) for a module in slot 3. ROUTe:CLOSe (@3911,3912,3913,3914) ROUTe:OPEN (@3911,3912,3913,3914) The Analog Bus relays (numbered s911, s912, s913, etc.) on the MUX modules are ignored if they are included in a range of channels.
- Page 15 Low Frequency Multiplexer Modules SCPI Programming Examples for the Multiplexer Modules Configuring a Module Example - Configuring a module for 2-wire or 1-wire mode: The following command configures a MUX module in slot 4 for 1-wire mode. Because you can configure only the 34923A and 34925A MUX modules (and the 34933A matrix module) for either 2-wire or 1-wire mode, an error is generated if you send this command to a slot that does not contain one of those three modules.

Low Frequency Multiplexer Modules 34924A 70-Channel Reed Multiplexer 34924A 70-Channel Reed Multiplexer The high-density 34924A 70-Channel Reed Multiplexer (70-Ch Reed MUX) is divided into two banks with 35 non-latching reed switches (channels 1-35 and 36-70) in each. This module also contains eight armature Analog Bus relays (channels 911-914 and 921-924), four on each bank that can connect the bank relays to the system Analog Buses. - Page 42 Low Frequency Multiplexer Modules This module is interlock protected, which means whenever the D-sub connector end of the modules is exposed, the Analog Bus relays immediately open and disconnect from the Analog Bus. For more information, see “Safety Interlock” page 11. Lifetime of relays is severely degraded as current or voltage goes up.

Page 49: Four-Wire Mode
Low Frequency Multiplexer Modules 34925A 40/80-Channel Optically-Isolated FET Multiplexer Four-Wire Mode - You may configure the 34925A as a single 20-channel 4-wire MUX. This configuration requires using neither external wiring nor connecting through the internal Analog Buses. For 4-wire resistance measurements, the instrument automatically pairs channel n on Bank 1 (source) with channel n+20 on Bank 2 (sense) to provide these connections. - Page 50 Low Frequency Multiplexer Modules - using the *RST command. This command resets the mainframe and all installed modules to the Factory configuration. This affects all installed modules. - cycling system power. This affects all installed modules. If the overvoltage situation is not resolved, clearing the overvoltage will result in a new overvoltage event occurring immediately.
