Bench Testing

CAUTION!

To protect the network analyzer, you must configure the SSP-PIN power combiner to block AC power from the input port.

To preserve signal quality, verify that all unused ports are terminated.

CAUTION!

Before you begin the following subsection, remove the input pad (JXP IN) before you apply power. This is necessary to avoid damage to the hybrids.

Measuring Forward Gain

This subsection provides instructions for measuring the full gain and the operational gain and flatness of the BT100.

To measure the full gain of the amplifier:

1Determine whether the power-supply jumper is positioned for 60 V or 90 V operation.

2Connect the BT100 to the test equipment as illustrated in Figure 4-1 and apply power.

3Verify that the DC voltage is 24 V ± 0.4 V and re-install the input pad.

4Apply the sweep signal and adjust test equipment as needed.

5Select manual gain by placing the drive control select jumper in the MAN position and turn the MANUAL LEVEL control (MAN) (Figure 2-13) fully clockwise.

6Measure the gain at mixed forward frequency using the procedure outlined in the operator manual provided with the test equipment in use.

To correct this number, add the insertion loss of the SSP-PIN power combiner (0.6 dB at 750 MHz, 0.7 dB at 870 MHz, or 1.1 dB at 1 GHz), the loss of the cable simulator at mixed forward frequency, and the loss of the cable equalizer (1.0 dB), if it is installed.

Example

The test equipment indicates a measured gain of 24 dB with a BT100 and the cable simulator is set to 20 dB.

1.1dB (power combiner)

+1.0 dB (cable equalizer)

+20.0 dB (cable simulator)

+24.0 dB (measured gain).

46.1dB (unit gain).

The result must meet advertised specifications for the unit.

The operational gain of the BT100 provides reduced gain capability. This enables the unit to operate in the proper region of the Bode board when it is controlled by the ADU or QADU drive units.

To measure the operational gain and flatness of the amplifier:
