A simplified block diagram of the HP B circuits is shown in Figure Integrator Output Mouse over to Zoom – Click to enlarge. Readjust V ADJ if necessary. If the signal is incorrect at any point, troubleshoot the associated circuits. These values are obtained in one of three ways: The only voltage adjustment is R in the V regulator.
The oven output frequency is 10 MHz. See terms – opens in a new window or tab. These signals are centered about ground by a compensating current equal to one-half the signal amplitude. As another example, if the output frequency were If the voltage is still incorrect, the fault lies prior to TP6. Ordering Information Now suppose an output of Signature Analysis Test o.
Measure voltages in the Q1 Ql 18 circuits.

Set controls as follows: If still bad, refer to Service Groups H and J. Reference Circuits Service Group G.
Also check for the correct enable signals from U This manual provides the best information we could find. This current is labeled Offset Correction in Figure The reset switch is a FET. These are also negative-going pulses, approximately 10 ts wide. Amplitude Modulation does not respond properly.
If A14C is changed, repeat steps d and g. The kHz signal is then differentiated to provide a narrow pulse to the Fractional N Phase Comparator.
This item will ship to United Statesbut the seller has not specified shipping options. Be sure sercice reconnect cable 23 to AI4J Basic Biock Diagram, Logic Circuits.
To obtain a part that is not listed, include: Ramp polarity is determined by the ramp polarity gate. Have one to sell? It multiplies the waveform by the amplitude value that U latched on to.
Up to this point, we have considered only the situation where N is a whole number consisting of three manua. This process is repeated through the twelve input lines to the matrix. The processor, ROM, and address bus must be working for this test to nm.
Press the Local key to ejdt this special test. Phase Accumulation If only srvice ramp functions are not operating properly, the trouble is probably in the ramp reset circuits.
If a voltage measured in step g is out of tolerance, repeat the amplitude flatness sedvice justment with the at both lOVp-p and 3Vp-p until all voltages are within tolerance.
Repeat sergice d and g. Measure voltage level at A3U18 pin 9. Amplitude Control Circuitry U is a 30D totem pole line driver capable of driving a standard 50D cable. If the signal at U31 pins 5 and 9 is correct but pins 6 and 8 are always low, it is possible that U32 could be defective. Set the to 10 MHz. It takes the about 50 milliseconds to make this change.

Earlier versions of this instrument, however, differ in design and appearance from those currently being produced. An instrument such as the HP A Signature Analyzer compresses the data at a given point during a controlled time span window and displays ssrvice resulting four-character signature. An over-voltage protection circuit in the unregulated -i-5V supply prevents the voltage from becoming high enough to damage the supply circuits.
