    Circuit Descriptions Agilent 89640/89641 circuit description 89605 Input Module The 89605 Input module accepts the input signal and passes it through a 0-to-50 dB attenuator (5 dB steps). In baseband mode (0 to 36 MHz), the signal is routed directly to the E1439 module, by-passing the E2730/E2731 module. In RF mode (36 MHz to 2.7 GHz or 6 GHz), the signal is routed to the E2730/E2731 RF Tuner.
  • Page 89 Circuit Descriptions Agilent 89640/89641 circuit description Triggering For external trigger mode, a trigger signal must be supplied at the Ext Trigger connector on the front panel. This input is AC-coupled with an impedance of 1K ohm so any signal with a sharp rising or falling transition greater than 100 mV (for example, TTL or ECL logic) can be used as an external trigger source.
