The 1200 SUPER S has two internal modulation sources. There is a 1 KHz fixed tone generator and a variable tone generator. Additionally, external modulation or a microphone can be used as a modulation source. These modulations can be used to modulate the RF Signal as FM or AM modulation types. Generate Mode testing that can be performed by the 1200 SUPER $ includes: Receiver Sensitivity Receiver Audio Distortion Receiver Audio Output Level Receiver IF Bandwidth Modulation Acceptance RECEIVE MODE In Receive Mode, the 1200 SUPER S is an RF Receiver with the ability to measure a Transmitter using internal testing abilities such as a Spectrum Analyzer, Oscilloscope, Modulation Meter, Relative Signal Strength Meter, Wattmeter (average and peak), Distortion Meter, Frequency Error Meter, SINAD Meter and DVM. In Receive Mode, the I kHz and Variable Tone Generators are also available for use as audio sources for the Transmitter Under Test. Receive Mode testing that can be performed by the 1200 SUPER S includes: Transmitter Modulation Level ‘Transmitter Power (Average or Peak) Transmitter Frequency Error ‘Transmitter SINAD Transmitter Distortion DUPLEX MODE In DUPLEX MODE, the 1200 SUPER S$ acts as both Generator and Receiver to test both sides of 4 Duplex System. The 1200 SUPER S Generator is limited to two levels, Low and High. The frequency for the 1200 SUPER S Generator is offset by an operator defined Offset Value from the 1200 SUPER S Receiver Frequency. Metering capabilities in DUPLEX MODE are the same as in RECEIVE MODE. DUPLEX GENERATE MODE In DUPLEX GENERATE MODE, the 1200 SUPER S$ acts as a Generator to test the receiver section of a Duplex System. Operation in this mode is identical to GENERATE MODE only the Frequency of transmission is the Offset Value added to the RF Value. Metering capabilities in DUPLEX GENERATE MODE are the same as in GENERATE MODE. Automatic RECEIVE MODE change over on detection of 100 mW at the T/R port is disabled. 11.2 TO INSTALL THE 1200 SUPER S 1.2.1 AC POWER INSTALLATION SETTING 120/240 VAC SWITCH ‘SCREWS SWITCH COVER zas0001 Prior to installation of ac power, the operator must verify that the 120/240 VAC Switch is properly set for the power source to be used.
