This general purpose board was created for high quality analog muxing/demuxing for demanding measurement applications.

8CH 4IO HF Analog Mux Board

Characteristics

CH1IO1 0..200MHz plot
CH1IO1 0..8GHz plot
Relays datasheet excerpt
  • 256x100mm 8 layers PCB
  • 8 <-> 1 channels
  • 4 I/O per channels (ground commuted with the signal, so no common ground)
  • Bandwidth : 0...200MHz (best use : 0...10MHz, see plot below)
  • SMA or SMB connectors
  • Signal relay based solution
  • Balanced tree routage (same trace distance for any commuted channel)
  • 50Ohms impedance controlled shielded coaxial traces
  • 1x LED per channel (light when selected) + 1x power LED.
  • 1x 2mm-pitched 2x6 connector.

Power supply / driving considerations

This board doesn't have any driving circuit on it.

Actually, there is 3 ways to drive the board :

  • A basic FPGA board, MFSRELAYCTRL, for HVME16 or any other control buses.
  • It can be driven with a NI USB box through a driver board too.
  • Finally, active channel can be manually switched via a basic switches box.
Control board : MFSRELAYCTRL
Control board for use with NI boxes
Control box - switches only ;-)

The following signals can be found on the connector :

Connector

Vin must be in accordance with the nominal voltage of the soldered relay (typically +5.0V).

Changelog / Known issues

  • None.

Contacts / Collaborators

This board was initially targeted for Joseph Moerschell's projects (MFS, gal's and mlo's master thesis).
