HP HP Procedure: Abort Message This check determines whether or not the Signal Generator becomes unaddressed when it receives the Abort message.
Remove the Line Voltage Selection Cam 8656h fingers. Changes in these adjustments can affect other adjustments, especially level and modulafion accuracies. The Signal Generator must have a minute warmup.
If you wish to measure the phase noise level of the Signal Generator at other center frequency settings after this test is completed, change the center frequency on the reference source to the desired frequency.
Check Digit] 2 A22 6 10 9 3 2 A complete list of ASCII characters with conversions to binary, octal, decimal, and hexadecimal is provided in Table The basic unit for amplitude in the Signal Generator is dBm.
Protects the signal generator mnual applications of op to 25 watts of RF power from a 50Q source to MHz into generator output; DC voltage cannot exceed 25 V. Exam pies Set the output amplitude to — The prefix is the same for all identical instruments.
It takes about ms for the modulation accuracy AM or FM to be within tolerance from the time the modulation audio oscillator is initially turned on.
Frequency kHz Amplitude 0. When addressed to listen, the Signal Generator responds to the following messages: Each is discussed in detail further on in this section.
Hewlett-Packard B Signal Generator
Step the frequency down 50 MHz to MHz. The Data message that is sent will cause the 7 least significant HP-IB data lines to be placed in both their true and false states. Set the amplitude of the Signal Generator under test and turn off the RF signal source. If necessary, Adjust the amplitude and offset of the function generator until the swept IF signal displayed on the spectrum analyzer starts just at MHz and stops just at MHz.
Set the HP B amplitude down to —3 dBm. Example Set a carrier frequency increment of I MHz. Carrier Center Frequency Frequency Accuracy 0. T Distortion Analyzer Distortion Range: The detected beat notes are monitored with an oscilloscope and the,and MHz Notch Filters are adjusted to minimize their associated beat notes. You will always return to this menu when you exit the selected function.
During an RF amplitude change, the final level is always approached from a lower level. Carrier parameters are set using a Function-Data-Units sequence of program codes, while modulation parameters are set using a Source-Function-Data-Units sequence of program codes.
There is a program code that corresponds to nearly every front-panel key. The level should decrease in relatively uniform 1 dB steps. If you operate or service instruments of different serial prefixes, we strongly recommend that you join this service immediately to ensure that your manual U kept current. Refer to Hgure The displayed demodulated signal should be a sine wave with a period of 1 ms!
However, the front-panel ADRS h remains lit if the Signal Generator is still being addressed to listen whether in remote or local operation.
The pulse duration is approximately 15 ms at the same level as the CW level.
Verify that the measured results do not exceed the limits specified. Center Frequency Accuracy in dc Mode: Adjust the spectrum analyzer as necessary to duplay the output signal from the Signal Generator. Increment the HP frequency down to 99 MHz. Comments You can save up to complete front-panel set-ups exclusive of increment settings. If die increment value change is set manhal a value that would cause the Signal Generator to exceed a minimum or maximum range, the step-up and step-down key associated with that function become inoperative.
This is because when the Amplitude or Frequency is changed when Pulse Modulation is selected, the HP B performs a calibration on the output level. An instrument manufactured after the printing of this manual may have a serial prefix that is not listed on the title page.
Use a strong shipping container. Refer to Figure for an example of the oscilloscope measurement display. Repeat step 1 and 2 until all the set-ups are saved.

Data can be any number of arbitrary length in fixed point notation. Continue to increase the carrier frequency to the maximum value listed 86656b the following table: Function Vdc Range 20 V 2. 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.
Press the Instr Params key. Hl performed at these frequencies wiU verify that in all probability, the instrument meets Us specifications.

The data entry mode is established when the Attentior bus control line ATN is false. When handling or servicing equipment manul static sensitive devices, adequate precautions must be taken to prevent device damage or destruction.
The Signal Generator is protected against reverse power applications up to 50 watts. The initialized value of each stored increment for the Signal Generator is listed below:
