The instrument should be stored in a clean, dry environment. Amplitude Modulation Distortion 9. Service Group O – Power Supplies The 6 dB is a correction factor compensating for the folding action of the mixer.

Disconnect the 15 kHz filter output from the digital voltmeter and connect it to the ac voltmeter. Set CRO as follows: Set tlie A as follows: Determine the minimum and maximum allowable voltages at each point by subtracting and adding 0. Devices which communicate along the interface bus fall into three basic categories. This procedure tests the harmonic distortion of the A sine wave output against the following specifications from Table The preceding instruments do not have C Change oscilloscope vertical gain as necessary to observe the signal.

In both cases the controller places the bus in the command mode to execute the message. np

Because string variables ,anual both alpha and numeric characters, the resulting printout includes the mnemonics and delimiters units. Frequencies above kHz Model A nn. Using the Modify keys, adjust the phase until the counter reads approximately nanoseconds.


Adjust Y offset in A3R60 to null out the sine wave signal on the display. This Test Record lists all of the tested specifica- Lions and the acceptable limits.

HP 3325A Synthesizer/Function Generator Operating and Service Manual

Set the A frequency to 5. Maximum output is 10 V p-p. All spurious non-harmonic signals should be at least 70dB below the fundamental. Electronic counter should indicate 10 Zero volts or dc offset voltage, see Paragraph Maximum and minimum amplitudes are shown in Table If you find any mistakes or if you.

To be distributed in accordance with IDNrequirements for calibration procedure TB The following equation may be used to determine the approximate maximum marker frequency: A list of these offices is provided at the end manua, this manual.


Set the A frequency to 20MHz. Change the above equation for determining maximum dc offset to the following: Several devices may be assigned to the 33255a bit and level, causing their response bits to be logically ORed or ANDed. The oscilloscope should display two square waves, approximately five divisions peak-to- peak, d.

This bit 3235a be monitored by the controller to determine when the A is ready for more data. Change attenuator to 12 dB. The following environmental limitations apply to both storage and shipment: The oscilloscope display should show a sine wave four divisions peak-to-peak, one cycle per division.


Turn A to ON. Electronic counter -hp- Model A a.

NOTE Calculate the values of a j and a 0 to at least five decimal places. The high voltage output is selected by pressing the key in the lower right corner of the front panel. Standard output impedance is 50 ohms. Enables all service request conditions. This program sets up sweep parameters and initiates a single sweep. X Drive Linearity Test. Continuous sweep is start to stop, start to stop, etc. Replace the screw in the oven assembly and repeat Step e.

The kit is shipped with the instrument if Option is also ordered. Change A function to negative slope ramp. To remove the filter, disconnect ac power from the instrument and remove the four nuts that secure the filter retainer.

However, to achieve manjal system performance, proper voltage levels and timing relationships must be maintained.

Direct current power line. The following backdating information pertains to the -f- N. An action a device performs in response to information sent on the HP-IB. Press the Negative Ramp function on the A. Without changing the reference level, change the spectrum analyzer center frequency to
