Section 4 OPERATING INSTRUCTIONS

4.2.7 Tracking

When the key is pressed, the LED inside the key lights and

the instrument enters the tracking mode.

When tracking, the MP1763C must be connected to an

MP1764A/C by a GPIB.

When the PATTERN LOADING lamp lights, the data is

read and the keys are disabled.

Tracking can be performed from both the transmitter and receiver. However, one of them must be set as the master. As a

result, tracking cannot be performed concurrently from the transmitter and receiver.

Turn on SYSTEM CONTROL of the Dip switch on the rear of the master instrument to perform tracking. (Turn off

SYSTEM CONTROL of the controlled side.)

In addition, set GPIB ADDRESS of the controlled side to GPIB ADDRESS of the master side + 2.

Note: The Dip switch on the rear panel for setting GPIB address is covered with the panel and fasten with screws to

decrease the radio active radiation.

To change the address, remove the panel for the setting.

When tracking is on, the setting of the transmitter (or receiver) is changed each time the setting of the receiver (or transmit-

ter) set as the master is changed. Therefore, each time a key is operated on the master side, operation disabled state occurs .

(Especially, operation is disabled for more than ten seconds when the bit length of the program is long.) To avoid this

condition, turn off tracking before changing the setting of the master side.
