CG635 Synthesized Clock Generator

A host computer interfaced to the CG635 can perform virtually any operation that is
accessible from the front panel. Programming the CG635 is discussed in the CG635
Remote Programming chapter.

RS-232

The CG635 comes standard with an RS-232 communications port. The RS-232 interface
connector is a standard 9 pin, type D, female connector configured as a DCE (transmit on
pin 3, receive on pin 2). The communication parameters are fixed at: 9600 Baud, 8 Data
bits, 1 Stop bit, No Parity, RTS/CTS Hardware Flow Control.

Before attempting to communicate with the CG635 over RS-232, the port must be
enabled via the front panel. Do this by sequentially pressing the following keys located in
the ENTRY section: ‘SHIFT’, ‘RS-232’, ‘Hz’.

A host computer interfaced to the CG635 can perform virtually any operation that is
accessible from the front panel. Programming the CG635 is discussed in the CG635
Remote Programming chapter.

Chassis Ground

Use this grounding lug to connect the CG635 chassis directly to facility ground

Timebase

10 MHz IN

The CG635 provides a 10 MHz BNC input for synchronizing its internal clock to an
external 10 MHz reference. The external reference should provide greater than 0.5 V

pp

into a 1 k

ȍ

impedance. The CG635 will automatically detect the presence of an external

10 MHz reference and lock to it if possible. If the CG635 is unable to lock to the external
reference, the front-panel UNLK LED will turn on and stay on until the CG635 either
successfully locks to the external reference or the reference is removed.

10 MHz OUT

The CG635 provides a 10 MHz BNC output for synchronizing other instrumentation to
the CG635’s timebase.

T

mod

Input

The CG635 clock edges can be modulated over ±5 ns by providing a modulation voltage
to the T

mod

BNC input. The input is calibrated to provide 1 ns of modulation for 1 volt of

input swing. The input can accept voltages of ±5 V. Positive inputs advance the clock
outputs, negative inputs retard the clock outputs.

The T

mod

input can be very useful for characterizing a circuit’s susceptibility to

timing jitter.
