Change power supply to put Thus the signals at the emitters and bases of Q8 and Q18 are in phase and the collector signals are degrees out of phase to provide push-pull deflection. Fault – internal mains fuse blown, fixed in 5 minutes and now a very handy instrument for all sorts of AF work, especially modulation response analysis and that sort or thing. Blade Tuning Tools Scan Generator and Trigger Circuits.

Calibrator Amplitude Test Setup New parts list and schematic for instruments with serial prefix and lower. For wide spectrum analysis, the operator can use the preset scan of the RF Section used, or for a more detailed study, the spectrum width can be progressively narrowed. Add up total attenuation. Horizontal Scan Check and Adjustment The instrument controls are arranged for easy operation. Connect the test setup shown in Figureturn analyzer power ON, and set controls as follows: Product price, specification, warranty and availability subject to change without notice.

When the kHz bandwidth is selected all four stages are bypassed and the signal is coupled directly to the output amplifier. Part A shows the wafer as it actually appears.

Note error from 1. The four stages are identical except that the fourth stage Ql has an adjustable resistor in the feedback path. The plugs are keyed so that yp will go on cor- rectly and will not make contact upside down.

Reinstall A4 Crystal Filter Assembly.
