LEVELED SINE WAVE GENERATOR.
The TEKTRONIX SG 504 provides a constant-amplitude sine wave over a frequency range from 245 MHz to 1 050 MHz. Amplitude-reference sine waves of .05 M Hz or 6.0 MHz (selected by internal switch) are provided. The output head has an output impedance of 50 ohms. The peak-topeak voltage from the output head is adj usted by a calibrated five-turn potentiometer. The SG 504 Leveled Sine Wave Generator is desig ned for use in the TM 500 series power modules.
The front-panel FREQUENCY MONITOR OUT connector provides at least a 0.3 V peak-to-peak signal at the selected output frequency (245 to 1 050 MHz) for monitoring or external triggering. There is also a provision for frequency modulating the 245 to 1 050 MHz output signal. When lit, the U N LEVELED light indicates a mismatched load or when the OUTPUT AMPLITUDE front-panel control should be turned counterclockwise. When the output head is disconnected from the front panel, the UN LEVELED light is also illuminated.
Rear interface connections are provided for the FM INPUT, FREQUENCY MONITOR OUT, and amplitude control. If the rear interface is used, these front panel features must be disconnected. They cannot both be used at once. For further information about the interface assignments, see Section 4, Maintenance and Interfacing I nformation, of this manual.
Align the SG 504 chassis with the upper and lower guides of the selected com partment. Push the module in and press firmly to seat the circuit board in the interconnecting jack.
To rem ove the SG 504, pull on the release latch located in the l ower left corner, until the interconnecting jack disengages and the SG 504 wi ll slide out.
