Describes any miscellaneous information or information to clarify the feature or function capabilities. For each frequency measure the maunal in amplitude as the HP B is pulsed on and off.

Hold the end of the loop antenna cylinder in contact with the front surfaces of the Signal Generator.

Step the frequency up 50 MHz to MHz, These two actions combine to place the Signal Generator 866b remote operation. To change the input impedance use mmanual following procedure: Refer to Hgure Connect equipment as shown in Figurefor the signal path shown as below.

Adjust the spectrum analyzer as necessary to duplay the output signal from the Signal Generator. Then remove the top cover. With Pulse modulation fast modethe internal-leveling routine is calibrated directly into the load. Hl test sensitive loads. Full text of ” HP: You can set the HP-IB address to any one of 31 valid addresses in the range 00 to 30 decimal. Protects the signal generator from applications of op to 25 watts of RF power from a 50Q source to MHz into generator output; DC voltage cannot exceed 25 V.

Four simultaneous modulation signals, two AM and two FM, may be selected. The Rise and Fall Time should manul within the limits shown in the Table. All signals and noise should be below the reference graticule line i.

Set the AM depth to the values listed in the following table and verify that the measured results do not exceed the limits specified. Amplitude function remains selected until: Check that the Hz oscillator level is within 0. This means that in high cycle applications, where the frequency or amplitude of the HP SB is constantly modihed, mznual the life of the attenuator may be reduced. Check your local country regulatory requirements for the disposal of lithium batteries.

Increase the output of the test oscillator by rotating the Amplitude Coarse control clockwise until the measuring receiver indicates Remove the top cower. When this is set to position 1, the input impedance is set to 50 ohms; when it is set to position 2, the input impedance is set to high impedance. Record the maximum variation highest reading — lowest reading. Set the output amplitude of the Signal Generator to — The two MHz Notch Hlters are in the circuit all of the time.

Table lists manuql test equipment that can be used.

Verify that the measured results do not exceed the limits specified. Local Operation Local Capability. Performing ttis feature places the Signal Generator in the Amplitude Data entry mode, and clears any previously selected function. Center Frequency Accuracy majual dc Mode: If external reference is used, ouput mil the same frequency. Send the Local Lockout message. Select pad values for —8 dBm to mixer. Unused or unidentifiable characters are ignored, 3.

NOTE The use of a screen room may mnual necessary to reduce external radiated interference. Initial Setup The test setup is the same for all of the checks. Modulation Test Setup 2, Set the measuring receiver as follows: Connect the digital multimeter to A13J2 A13J2 pin i. FM Distortion at Hz and 1 kHz rates: The Signal Generator is preset, unpluggecL or switched to standby, A one key sequence acts as a select between the two internal modulation sources.

To 10 kHz with uncalibrated output and modulation. Unless otherwise stated the information applies manuak all three Manuak Generators. NOTE If the noise level measured by the HP A exceeds the Signal Generator’s specified noise level and the exact noise level of the reference source is not known, the exact level of eadi source should be determined by measuring each source against a third signal source and comparing the measurement results for all three measurements.

Each is discussed in detail further on in this section. The source of reverse power must be removed.

Carrier frequencies below kHz will result in an uncalibrated output amplitude. Upon entering that value the measuring receiver will also change the center frequency t y that amount, the Signal Generator should be stepped to match. Verify that the Line Voltage Selection Cam is matched to the power source. Then press a Function key, the desired Data keys, and the valid Units key. An FM deviation change typically occurs 60 ms after the final terminator Units Mqnual triggers the change.

Send the listen address to the Signal Generator. Do not use repaired fuses or short circuited fuse holders.
