Find the average IF level by dividing the difference between the maximum and minimum IF levels by 2, and then adding the result to the minimum IF level. This is stamped on the serial number plate attached to the rear panel of the instrument.

If shipping to a Hewlett-Packard office or service center, attach a tag indicating the type of service required, return address, model number, and full serial number.

The minus sign is only applicable during Amplitude Data entries. In each case a finite amount of time passes from the command manual or computer generated until the required output occurs. Press the blue [shift 1 key, and then press and hold the [local adrs key. Table a and Table b summarizes these input data restrictions. If the calibration pulse will cause damage, then select Pulse Modulation.

Frequency Counter Mode Level Modulation 2. Indications Each time you press the SEQ key, the next front-panel set-up is recalled and the Signal Generator is changed to the new set-up.

The checks are intended to be as independent of one another as possible, since each begins with the Signal Generator being reset to its initialized condition.

Set the HP B amplitude down to —3 dBm. All tests can be performed without access to the interior of the instrument, A simpler operational test is included in Section 3 under User Confidence Tests.

Comments You can save up to front-panel set-ups exclusive of increment settings. This means that in high cycle applications, where the frequency or amplitude of the HP SB is constantly modihed, then the life of the attenuator may be reduced. Repeat steps 4,5,6 and 7 until both readings are within the required tolerance. The HI ALC mode no drop-out mode is volatile and cannot be saved as part of a storage register, however, recalling a register or sequence wiO not change the current ALC mode.

Protects the signal generator from applications of up to 50 watts of RF power from a 50fi source to MHz into generator output; DC voltage cannot exceed 25 V.

Minimum and maximum allowable increment values for each of the four main functions are listed below. Nevertheless, it is suggested that the first four checks be performed in order before any other check. Enter an appropriate graph title for your test. The validity of these checks is based on the following assumptions: Typical total FM cfistorfion harmonic and nen-harmonfc is less that 1.

Description SWR is verified by comparing the reflected power frequencies 0. Adjustment location diagrams and removal and disassembly instructions are provided at the end of this section. All signals and noise should be below the reference graticule line i.

In this case, register 10 would be recalled. FM peak deviation Data entries are rejected if they would cause the selected carrier frequency to be out-of-range. Set the function generator as follows: Maanual error code remains displayed until any front panel key is pressed. The software time may vary considerably depending on the function.

Section 3 Operation, provides information for local and remote operation. Remove the Line Voltage Selection Cam wim fingers. Servicing instructions are for use by service trained personnel only. The measurement resttlts will stiU reflect the noise level of the Signal Generator under test.

The HP B is set at the factory manuwl high impedance, refer to section 2 of the Operation and Calibration Manual if you want to set 865b input impedance to 50S1. When notch filter adjustments are complete, return A4W4 to the lock position. Output amplitude resolution is 0.

Change the display to units of dB pV. Frequency HP B Plug in the power cable.
