The Tektronix SI5010 is a GPIB-controllable 50 Ω BNC switch matrix plug-in for the TM5000 system. It can only be controlled via GPIB − the front panel only provides an "Inst ID" button whose function is also software controlled.


The −3 dB frequency is 350 MHz for transmission through the switch. The isolation between channels is 40 dB at 100 MHz. Switching is performed using relays, not semiconductor switches.

  • Software Reconfigurable as:
    • 16 Channel to 1
    • dual 8 Channel to 1
    • quad 4 Channel to1
  • Buffered mode for unattended (controllerless) operation
  • Real time clock
  • Triggered events


The SI5010 shares the GPIB/CPU board A20 (670-7199-00) with the MI5010.
