Adjustments Required After Repair. A check of this current is made as follows: By turning on the HP B without activating the function of concern. This frequency tests the API 3 circuit.

Monitor pin 9 of U36 with the oscilloscope. Figure illustrates this process for the example we are using. During each scan cycle, the events shown in Figure 33325b concurrently.

Sync Comparator and Driver. The VCO circuit is covered by a shield consisting of a flat cover and an extrusion. Be careful to keep the connectors clean. Mahual method for obtaining this frequency is illustrated in Figure In each of the last five positions of the bit shift register, the high bit that is being shifted through enables one of five sets of annunciators. During continuous sweep, the ramp is reset at the start of sweep down.

Disconnect the external power supply. Control Circuits Service Group C. Following a single sweep, the X Drive ramp remains essentially at lOV until reset prior to the start of another sweep.

Press local to quit. Simplified Illustration of Triangle Generation Code for manufacturer of the part. Ramps are reset by manua, digital Phase Msnual at frequencies below Hz, and by the analog output Level Comparator at frequencies of Hz and higher.

Shift DegmVrms Self Test 5 1 c. If input pulses are not present, go to Control Logic troubleshooting. DBS and DB15 should be low, all others should be high. Using the disconnected end of the HP-IB cable, connect one pin at a time to pin 24 while watching the display. If the waveform is not correct, continue troubleshooting with Step b. Discrete Sweep The enhanced feature set of mmanual HP B includes segment discrete sweep capability which allows arbitrarily defined multi-segment linear or stepped sweeps and tone sequences.

Readjust V ADJ if necessary.

Providing the finest test equipment solutions since 1992

To keep the manual up-to-date, periodically request the most recent supplement, available from the nearest Hewlett-Packard office see sales and support of- fices listing at the back of this manual. This should be at a TTL high level. If the signals are not present, check the oper- ation of the Fractional N chip U19 and check maual the latch clock coming from U22 pin 6.

If the test passes, plug in one connector at a time and re-run the test to determine the assembly causing this test to feul. This returns the phase detector input to kHz, and the loop is again Test Equipment for Troubleshooting This biases Q into conduction. Change the frequency to 5 Hz.

Triangle and ramp waveshapes are also available with. The A14Q amplifier circuit supplies sine wave current to the output amplifier. The cycle start flip-flop is set by the Q output from the preload flip-flop and is cleared by the next trailing edge of the chip clock signal.


Power must be cycled after running this test to restore HP-IB operation. Where maintenance can be performed without power applied, the power should be removed. In sine function, the sine wave from the mlypr passes through a current amplifier to the output amplifier. Manuall other words, if the 5 key has been pressed, only one 5 will be processed even though the key is held through more than one keyboard scan cycle. The voltages at Q emitters should always be identical.

Writes data to the modulation source waveform RAM, then reads it back.

Used for a signal common, as well as providing protection against electrical shock in case of a fault. If the frequency synthesis circuits are operating jp, both pins will be negative. This information is updated every 10 microseconds. The fast rise times normally require precise terminations, but the RC filter at the output slows the edges just enough to prevent undesirable reflections e.

Used with field wiring terminals to in- dicate the terminal which must be connected to ground before operating equipment. The oven output frequency is 10 MHz.

The Function Integrity Flag tells the processor which ramp reset method analog or digital is being used.
