Pentek Model 78661 Installation Manual

Rev.: 1.7

2.12

XMC Panel Connections

(continued)

2.12.2

Trigger Input Connector

TRIG

The front panel has one SSMC coaxial connector, labeled

TRIG

, for input of

an external trigger. The external trigger signal must be an LVTTL signal.

The trigger input can be used as a gate or trigger for A/D signal processing.
This input is enabled using Sync Bus Control Register 2 TTL SRC bits (see
Model 71660 Operating Manual).

2.12.3

Analog Input Connectors

1, IN 2, IN 3, IN 4

The front panel has four SSMC coaxial connectors for analog signal inputs,
labeled

IN 1,

, and

, one for each ADC input channel.

The analog input signal has a full−scale level of +8 dBm. Each input drives
an RF transformer, with 50

input impedance.

Note

The front panel TRIG input is 5V tolerant but it must NOT have any

negative voltage applied. It is terminated with a 392

−

Ohm resistor to 3.3V

and a 392

−

Ohm resistor to ground.
