Check the specifications of any equipment which the HP B is being used to test, to ensure that the calibration pulse will not cause any damage.
8656B Synthesized Signal Generator, 0.1 to 990 MHz
Parameter Vafue Carrier Frequency Adjustment Locations Adjustment 24 I r. The beat note levels should resemble those shown for channel 2 in Figure It may be incomplete or contain dated information, and the scan quality may not be ideal.
This maximum limit includes any embedded decimal points. The instrument and all related documentation must be reviewed for familiarization with safety markings and instructions before operation.
It is assumed that the Signal Generator is able to both handshake and recognize its own address. Initial Setup The test setup is the same for all of the checks.
The reference is established on the spectrum analyzer display. Furthermore, less than 1. Such maintenance should be performed only by service-trained personnel who are aware of the hazards involved for example, fire and electrical shock. If you operate or service instruments of different serial prefixes, we strongly h; that you join this service immediately to ensure that your manual U kept current.
Center Frequency Deviation kHz 0. The tilt stands raise the front of the Signal Generator for easier viewing of the front-panel. Refer to Figure for an example of the oscilloscope measurement display. Provides 2 additional years of return-to-HP hardware service support for 2nd and 3rd years Indications The carrier frequency phase changes in I degr ee steps each time the keystroke sequence is followed. With Pulse Modulation normal modethe internal-leveling routine is calibrated into the attenuator.
NOTE fVhen you select 8656g timebase input or output frequency, the Signal Generator timebase output or timebase input, will be set for the same frequency.

Unsolder the end of the selection link and resolder it in the appropriate position for the time base output or the external time base signal you require. Voltage Offset Adjustment Adjustment 20 must be performed before per- forming this adjmtment.
Only one internal modulation source can be selected at any time either Hz or 1 kHz. I I A I Contents 1.
Set the Signal Generator frequency and select the measuring receiver high-pass and low-pass filters as indicated in the following table. Set the frequency counter as follows: The protective action must not be negated by the use of an extension cord power cable without a protective conductor grounding.
All Signal Generator settings remain unchanged when the transition from local-to-remote operation occurs.
Set the test oscillator as follows: Function Vac Range mV f. Same as time base used. Comments The Pulse Input Impedance can be selected for 50 ohms or high impedance.
The amplitude variation from maximum to minimum should not exceed 1 dB. Step the Signal Generator and measuring receiver through the following frequency ranges: Directions to Modify Amplitude: HP does not warrant that the operation of the instrument, or software, or ftrmware will be uninterrupted or error free. Pulse Modulation Option Indicator Accuracy internal rates: Connect the digital multimeter to A13J2 pin 5.
Seal the manial container securely.

With Optiona 10 MHz crystal reference is available for increased accuracy and stability. The maximum and mininaum voltages in dB are read from the spectrum 865b6 to compute the SWR using the equation listed below. The Remote message is comprised of two parts. Read the maximum and minimum power levels from the spectrum analyzer and substitute their value in the following equation and solve for the SWR of the Signal Generator.
A complete list of ASCII characters with conversions to binary, octal, decimal, and hexadecimal is provided in Table An FM deviation change typically occurs 60 ms after the final terminator Units Key triggers the change.
Set the spectrum analyzer frequency span to 25 kHz.
Increment the HP frequency down to 99 MHz.
