3.6 INITIAL TURN ON AND WARM-UP PROCEDURE
Install the TWTA as discussed in Section 3.2 Provide an RF generator to the RF input Type N connector
A2J1. Set RF generator level below -50 dBm and set desired frequency in specified range. Connect a load
suitable for 1000 watts continuous operation to the output S-C connector. The load VSWR should be less than
2.0:1 A power meter and suitable attenuators may be connected to the RF forward sample out port A2J2.
Refer to the RF sample port calibration factors on the rear of the unit or on the
Info screen in MENU 2. These
show the relation between the amplifier output power and the RF sample port power as a function of
frequency. When only the power of the fundamental frequency is to be measured and when operating near
rated power use; filters, a frequency selective receiver, or a spectrum analyzer to reduce the harmonic content
of the measured level.
