Test Set Familiarization

The PORT CONNECTION Status LCD

The PORT CONNECTION Status LCD displays the following:

• Which test port is connected to the REFLECTION port

• Which test port is connected to the TRANSMISSION port

• The status (O = “Open”, L = “Low”) of each of the five control lines

(C5 through C1)

All test ports not displayed on the Status LCD are internally

terminated in 50 Ω.

The CONTROL LINES Connector

The 9-pin CONTROL LINES Connector provides the user with a way of

controlling either the Device Under Test (DUT) or other equipment. The

test set cannot source any current from this connector. Therefore, the

user must provide an external power supply and some additional

circuitry if he wishes to use the connector. Refer to“Using the Control

Lines Connector” on page 7-6 for further details.

CAUTION

Do not apply more than +22 Vdc to pins 1 through 5 of the CONTROL

LINES Connector.

CAUTION

Do not employ external circuitry that forces the test set to sink more

than 250 mA on any control line (pins 1 through 5 of the CONTROL

LINES Connector) when that line is commanded to the “Low” state

(+0.63 Vdc).
