Keysight 34970A/34972A User’s Guide 21
34904A 4x8 Two-Wire Matrix Switch
– 32 two-wire crosspoints
– Any combination of inputs and outputs can be connected at a time
– 300 V, 1 A switching
– For detailed information and a module diagram, see page 219.
Use this module to connect multiple instruments to multiple points on your
device under test at the same time. You can connect rows and columns between
multiple modules to build larger matrices such as 8x8 and 4x16, with up to 96
crosspoints in a single mainframe.
34905/6A Dual 4-Channel RF Multiplexers
– 34905A (50Ω) / 34906A (75Ω)
– 2 GHz bandwidth with on-board SMB connections
– 1 GHz bandwidth with SMB-to-BNC adapter cables provided
– For detailed information and a module diagram, see page 222.
These modules offer wideband switching capabilities for high frequency and
pulsed signals. Each module is organized in two independent banks of 4-to-1
multiplexers. Both modules offer low crosstalk and excellent insertion loss
performance. To create larger RF multiplexers, you can cascade multiple banks
together. Only one channel in each bank may be closed at a time.
34907A Multifunction Module
– Two 8-bit Digital Input/Output ports, 400 mA sink, 42 V open collector
– 100 kHz Totalize input with 1 Vpp sensitivity
– Two 16-bit, ±12 V Calibrated Analog Outputs
– For detailed information and module block diagrams, see page 223.
Use this module to sense status and control external devices such as solenoids,
power relays, and microwave switches. For greater flexibility, you can read digital
inputs and the count on the totalizer during a scan.
