Page 14: General Operation
Switch Configuration General Operation The 87406Q matrix switch consists of six ports which can be individually connected via internal microwave switches to form an RF path (see Figure 2- 1). When control inputs are sent to the switch, the internal diode logic and position sensing circuitry routes current to the appropriate solenoids to close or open the microwave switches based on the input state. - Page 15 Switch Configuration Figure 2-1 Keysight 87406Q block diagram Keysight 87406Q Operating and Service Manual...

Page 16: Driving The Switch
After the RF path is switched and latched, the drive current is interrupted by the N O T E electronic position-sensing circuitry. Pulsed control is not necessary, but if implemented, the pulse width must be 15 ms minimum to ensure the switch is fully latched. Keysight 87406Q Operating and Service Manual... -
