3325A Synthesizer/Function Generator

Electronic counter should indicate 10 Change A amplitude to mV p-p, and change oscilloscope vertical to. Harmonic Distortion relative to fundamental Fundamental Frequency 0. The specification in Table is: This h contains the procedures required to adjust the A to meet its specifications in Table Does not cause SRQ.

Sweep 3325s or linear, single or continuous without the phase discontinuities usually associated with synthesizers. Fully Programmable All necessary functions are programmable on the HP-IB, including frequency, amplitude, all functions, phase and dc offset, 33325a, all sweep parameters, amplitude cal and self-test, making the HP A a very versatile and powerful addition to automatic test systems. The preceding range of instruments contain the biasing circuitry for U14 shown in Figure General Interface Management Lines Read pos and neg peak voltages in the center of the screen.


Each entry parameter car. The A may be operated with an external reference to control the standard 30 MHz internal reference oscillator frequency. Single log sweep is a line- segmented log approximation in one-tenth decade seg- A Performance Test Record is located at the end of this section. Page 12 TB 15 Set frequency counter controls to measure frequency. Page 22 TB Figure 5. A unique method of triangle and ramp waveform generation provides excellent linearity.

The NOTE sign denotes important information. Thsi is not a User Manual. If the modify key is held, the digit will continue to increment or decrement after a slight delay.

Enter 20 MHz in the A. The total quantity of a part is given the first time the part number appears.

It is necessary merely to enter the numerical data followed by the V or mV delimiter. Automatically calibrates the amplitude and offset of the output signal see Paragraph Verify that all three 3325aa are between. No other device dependent data communications are permitted on the bus until the entire A program string has been accepted and all but the last character processed.

Other programs may then be entered. Instruments with Option do not have rear panel signal output. Protect the control panel with cardboard, d.

Oscilloscope -hp- Model A Function. Operational Verification msnual the following procedures: Performance Tests which compare the instrument operation to the specifications listed in Table Set DC voltmeter to IV range and ext trigger. Change A function to triangle. The following accessories are available for use with the Model A: The horizontal arrow keys select the digit to be modified indicated by a bright digitand the vertical arrow keys increment or decrement that digit.


This instrument was carefully inspected both mechanically and electrically before shipment.

A14 A4 Board Revisions. The characteristics of the two modes are: If the dc voltage measured in the MHz range is out of tolerance, increase or decrease the value of A14C as necessary, using the values shown in Table Line 3 The sweep decrement is also in.

Change A amplitude to 3Vp-p, and remove the voltage divider from the circuit. Control Circuits Service Group C. High Stability Reference Option Adjust the dc power supply output voltage to null out the sine wave signal on the display.

Amplitude Control Circuitry Serial a.

Providing the finest test equipment solutions since 1992

Connect the A signal output to an oscilloscope -hp- A with a load. Several steps arc needed to develop an HP-IB program.

If necessary, readjust X Drive A14R6turning clockwise to increase voltage and counterclockwise to decrease voltage. Concord, NH Signetics Corp. The following examples are given to illustrate the basic procedure for developing a program.
