Adding my pinout diagram for the H2565A hybrid attenuator for anyone who might
be able to use it.

Hi Rich,
This is useful. Your drawing shows pin 42 (GND/CAL) going to relay coils. Pin 46 (SIG_EN) should go to the coil and pin42 should be going to one of the relay contacts. K2 relay enables calibration path (input disconnected and GND/CAL signal is fed to input) if GND/CAL goes to K2 coil.
