Attenuators Relays and Pads. Replace any defective components. For the maximum ramp output frequency of 10 kHz: An instrument such as the HP A Signature Analyzer compresses the data at a given point during a controlled time span window and displays the resulting four-character signature.

If the voltage at the load is too low, for ex- ample, this sense voltage feedback causes the regulator to adjust its output to the correct voltage. If the instrument accepts and displays entries but there is neither a signal nor sync output, or both outputs are distorted, the trouble may be in the output amplifier circuit.

Set spectrum analyzer controls as follows: For additional information, see the Global Shipping Program terms and conditions – opens in a new window or tab. Lights all front panel LEDs.

This frequency tests the API 5 circuitry. If pulses appear at the input pins and clock inputs and the manula at the clear inputs pin 1 is high, replace the defective latch IC.

If all of the above signals are correct, check for the presence of input pulses at A21U19, pins 20 through The table next to U28 on the schematic relates the functions to the enable signal levels. Logic Troubleshooting by Signature Analysis. If the preset number in the 3rd Digit Counter was greater than one, the LSD Counter continues to servive, supplying an enable pulse to the 3rd Digit Counter each time it reaches zero.

Some schematics may use mnemonics that begin with L or H to designate active low or active high. When the supply is below 3. Measure the frequency seervice each of the following points in order, and determine the relationship to the VCO frequency at W3 step d.

U14 divides the 2 MHz reference by two.
