External Detector Gain Correction, Adjustment #103
This adjustment generates correction constants for the receiver to make both external
detector and internal broadband measurements. Perform this test whether or not you plan
to use external detectors.
In this test, an accurate ±0.5 V is provided to both the X and Y detector inputs by the
voltage reference source.
Required Equipment
NOTE If a voltage reference source is not available, connect the requested voltages
to the external detector connector as shown in Figure 2-3. Note that both a
positive and negative voltage are required simultaneously, and both must be
referenced to ground.
pin D = V+
pin C = V
pin K = GND
These voltages may be obtained from a dual power supply, however it is
possible to derive the required voltages from the external detector connector
itself.
pin B = 15 V with respect to GND (pin K)
pin A = +15 with respect to GND (pin K)
1. Cable 8120-5514 must be used with the voltage reference source box; the normal power
sensor cable will not work. (This cable is included as a part of 08712-60031.)
