Select a valid country. The reset switch servce a FET. The kHz signal is then differentiated to provide a narrow pulse to the Fractional N Phase Comparator. 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.

The effect of this adjustment can be observed only after another single sweep. The frequency synthesis circuits generate a sine wave at a frequency determined by digital information from the control circuits.

This frequency tests the API 5 circuitry. Adjust the delay to see the ramp reset jitter and read the positive ramp jitter in microseconds. Figure Figure Sign in to check out Check out as guest. Table is a dictionary of the mnemonics used for the HP B. Shipping cost cannot be calculated.

These voltages may be adjusted out of tolerance by Paragraph Step f, but it is not a cause for concern. If this were not done, the charge would continue to accumulate to the limit permitted by the power supplies and remain at that level nullifying the entire PLL scheme.

Servicing Information Alternating current power line. If any of the pulses are not present, check the fractional-N chip U19 for the proper signals. If the signal is good, proceed to step q.

This returns the phase detector input to kHz, and the loop is again Voltage levels should be the same as in Step c. If they are correct, troubleshoot the A26 assembly using this SA test.

Check for a -i- 5 V signature of Example 1 Example 2 Sine wave output 10 If the waveform is correct, the amplifier is probably operating correctly, and the problem may be in the Attenuator, Service Group L. Problems in the Amplitude and Offset control circuits are most easily located by measuring dc voltages. Performance Test Troubleshooting Guide 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.

Not a photocopy or CD. This should be at a TTL high level. You are servicce by the eBay Money Back Guarantee if you receive an item that is not as described in the listing.

Check U pin 8 for a 4 MHz clock signal. Set the frequency to 5 Use the Test Signal Flow Diagram Figure 8-C-l to help you determine the order to check the signatures and facilitate troubleshooting.

If the output frequency were These values are obtained in one of three ways: Where maintenance can be performed without power applied, the power should be removed. Please enter 5 or 9 numbers for the ZIP Code. Frequency Synthesis If the square, triangle, and ramp functions are inoperative, or if the DC Offset no ac func- tion is one-half the programmed level, the problem may be in Offset Control circuits U38B, Q, U41B,orQ Image not available Photos not available for this variation.

Placing a load on the output further improves reflection problems, but it decreases the signal amplitude to a level that may be just below valid TTL levels.

If the signal is incorrect, troubleshoot the API 4 sub-block and the U19 programming signals. Refer to eBay Return policy for more details. Three Signature Analysis tests are available for troubleshooting the Control circuits. All items are subject to prior sale. On the display, the number for A appears on the left side and the number for B appears on the right side. The fan filter must be inspected frequently and cleaned or replaced as necessary to permit the free flow of air through the instrument.

When replacing CRIOI, a good technique is to use four round toothpicks to position each of the four leads into place. No additional import charges at delivery! Only one of these inputs are active. The same high bit that is 3325bb through the bit shift register to scan the keyboard enables one of the eleven numeric display digits in each of Service Model the first eleven positions of the register.

Following repair of some circuits, certain adjustment procedures must be performed to assure proper operation manial the instrument. People who viewed this item also viewed.

Other offers may also be available. Program an instrument sweep from IkHz to 20MHz while monitoring the signal at the center connector of J Repeat Steps C through g until all readings are within the tolerances. On the Control assembly, check U6 and U7.
