The standard Model A provides selectable front or rear panel ohm signal outputs. Adjust Y offset in A3R60 to null out the sine wave mqnual on the display.

No circuit or comp, layout changes. Integrated Phase Noise Test. Integrator and Phase Modulation Circuitry Set the sine wave signal source A as follows: This range of instruments contain the integrator and phase modulation circuitry shown in Figure Negative Slope Ramp Frequency. However, because of the overrange capability of the A, the maximum frequency for each function is as shown below; Sine wave Square wave Triangle Positive slope ramp Negative slope ramp 20 Factor Peak-to-Peak Amplitude hanges: Change the A frequency to kHz.

The marker frequency may be set to any point within the sweep band up to within approximately microseconds of the stop frequency. Determine the nature of the program error.

Otherwise, both kits are available separately by their -hp- part numbers. An external reference may be used to phase Jock the internal 30 MHz reference see Paragraph Record the ac voltmeter reading dB scale. Mylar R rms. A Performance Test Record is located at the end of this section. If frequency counter does not indicate between High Voltage Output Option The dc digital voltmeter reading should be Valid EOS characters are: The minimum and maximum permissible dc offset voltages when the High Voltage Output is selected Option may be determined by multiplying the amplitude and offset values in Table by four.

Adjust Ref A3R30 for a counter display of No circuit or layout changes. To obtain a part that is not listed, include: Philadelphia, PA Littelfuse Inc. See Service Group C. These bandwidth modification keys do not operate in log sweep mode.

Al correspondence with Hewlett-Packard concerning this instrument should include the complete serial number.

Total quantity used in the instrument Qty column. For these instruments, the following Amplitude Calibration adjustment procedure should be used. Mixer Service Group H. The preceding range of instruments do not have R Concord, NH Signetics Corp. The instrument should be stored in a clean, dry environment.


Instrument and Manual Identification While the A is processing data it will accept and respond to universal commands. The phase is advanced or retarded with respect to the starting phase.

3325A Synthesizer/Function Generator

The effect of this 3325q can be observed only after another single sweep. Amplitude Accuracy at Frequencies up to kHz a. Output Amplifier Serial Numbers Remove the ohm feedthru termination and connect the A output directly to the digital voltmeter input.

This test compares the integrated phase noise to the specification in Tablewhich is: Change function to negative slope ramp and repeat Step c. Adjust nanual spectrum analyzer as follows:
