Page 12: Overview Of The 34934A
Overview of the 34934A 34934A High Density Matrix Module The 34934A is a 512 crosspoint matrix of non-latching reed switches, which you can operate in any of six different 1-wire topologies or three different 2-wire topologies. Larger matrices can be created from the base configurations by linking 34934A modules.
Page 13: Operating Considerations
Because of mainframe thermal and power-supply restrictions, you can close no more than 64 channels (crosspoint relays) on the 34934A at one time. If you try to close a 65th channel, an error will be generated from the 34980A, and the channel will remain open.
Page 14 Overview of the 34934A Connection to the 34980A Analog Buses This module does not internally connect to the 34980A mainframe’s four 2-wire (HI, LO) 300V-rated Analog Buses. – ABUS1 (MEAS) and ABUS2 (SENSE) connect to the internal DMM. – ABUS3 and ABUS4 are for signal-routing only, and do not connect to the DMM.

Page 18: Benefits Of Using The Terminal And Configuration Blocks With The 34934A
Chapter Benefits of Using the Terminal and Configuration Blocks with the 34934A You have three options for connecting field wiring to the 34934A: – Terminal Blocks – Configuration Blocks – Direct Wiring Terminal Blocks Terminal blocks provide convenient access through screw terminals to the rows and columns of the matrix.

Overview of the 34934A Configuration blocks can be used with a single 34934A. They can also be used in extended-row matrix configurations employing multiple 34934A modules; daisy-chain connections between the modules are made using the extension headers. For the 34934C-001, the D-Sub connector pin assignments are identical to the NOTE D-Sub connectors on the 34934A module.

Page 23: Practical Examples For Selecting A Matrix Configuration Mode
Overview of the 34934A Practical Examples for Selecting a Matrix Configuration Mode The 34934A provides a wealth of configuration options, using just one module or in combinations of up to eight modules in a single mainframe. Each module combines four electrically separate 4x32 matrices; the 4x32 matrix is the basic elemental component for all larger matrices which can be configured by jumper settings and wiring.
Page 24: 4X32 Matrices
You can select the 4x32 matrix configuration by setting jumpers on the appropriate terminal block or configuration block, or by D-Sub wiring. Once configured for 4x32, the 34934A creates four matrices, each with 128 crosspoint non-latching reed relays organized in a 4-row by 32-column configuration.
Page 25 SCPI paired commands (e.g. ROUT:OPEN:PAIR). A potential application of the 4x32 topology is to extend one 4x32 matrix to an adjacent 4x128 matrix (a second 34934A module) to create a 4x160 (1-wire) matrix with three independent 4x32 (1-wire) matrices.
Page 26 Overview of the 34934A See “Channel Numbering” on page 168 for the numbering scheme. 4x32 2-Wire Operation, Test Circuit Examples The two examples below each show a 2-wire circuit path. One path uses matrix 1 (left side of the 34934T-001 terminal block); the other path uses matrix 2 (right side of terminal block).
Page 27 Overview of the 34934A These examples introduce one of the SCPI paired commands; ROUTe:CLOSe:PAIR. With pair commands, you specify only the H channel numbers; but both the H and L channels of a pair are operated (e.g. opened or closed).

15). A potential application of the 4x64 1-wire topology is to extend one of the 4x64 matrices to an adjacent 4x128 matrix (a second 34934A module) to create a 4x192 (1-wire) matrix with an independent 4x64 (1-wire) matrix.
Page 29 Overview of the 34934A 4x64 1-Wire Operation, Test Circuit Examples The two examples below each show two 1-wire circuit paths. On MH: The upper example path connects a DUT on column C1 to an instrument on row R1, through one 100Ω series row-protection resistor. The lower path shows both DUT and instrument connected to columns, but through two resistors.

The terminal block connects to the 34934A’s two D-Sub connectors; it provides 12 blocks of 12 screw terminals each, and a 16x32 removable overlay (supplied with the 34934T-002) which provides guidance for field wiring the 16x32 matrices.

Page 236: Product Handling Recommendations For Maintaining > 10Gω Dc Isolation
Issue: Recent tests in a high temperature - high humidity environment have revealed that contaminants on the movable jumpers of the 34934A terminal block and configuration block may affect the published DC Isolation specification. Salts/ oils from fingertips can create electrical paths (< 10 GΩ) if these contaminants are transferred to the surfaces of adjacent jumpers in physical contact with one another.
Page 237 Handling - Expansion Cables: To avoid degradation of the DC isolation specification in applications involving multiple 34934A modules, the rows of the expansion cables connecting the 34934A modules should not touch. The figures below identify the expansion cable and cable location.
