The lowest-priced item in unused and unworn condition with absolutely no signs of wear. The item may be missing the original packaging such as the original box or bag or tags or in the original packaging but not sealed. The item may be a factory second or a new, unused item with defects or irregularities. See details for description of any imperfections. The Agilent or Hewlett Packard A is very reliable piece of equipment. It uses DDS techniques to create a stable, accurate output signal for clean, low distortion sine waves.

We have written the exercises in this chapter to prepare the function generator for use and help you get familiar with some of the front-panel operations. The bus address is displayed. Page 9 The function generator is shipped from the factory with a mAT fuse installed.
This is the correct fuse for all line voltages. See the next page if you need to change the power-line fuse. To replace the mAT fuse, order HP part number Page Remove the the assembly. Fuse: mAT for all line voltages HP Part Number: Rotate the line-voltage selector until the Replace the fuse-holder assembly in correct voltage appears in the window.
Then, rotate the handle to the desired position. Bench-top viewing positions Carrying position The following steps show you how to change the frequency to 1. Freq 1 Enable the frequency modify mode. The following steps show you how to change the amplitude to 50 mVrms. Ampl 1 Enable the amplitude modify mode. The following steps show you how to change the offset to —1. Page To Output A Stored Arbitrary Waveform Chapter 1 Quick Start To output a stored arbitrary waveform To output a stored arbitrary waveform There are five built-in arbitrary waveforms stored in non-volatile memory for your use.
You can output these waveforms directly from non-volatile memory. This enables you to recall the entire instrument configuration with just a few key presses from the front panel. The following steps show you how to store and recall a state. Recall 5 Recall the stored instrument state. To recall the stored state, you must use the same memory location used previously to store the state.
Page 24 Chapter 2 Front-Panel Menu Operation A front-panel menu tutorial A front-panel menu tutorial This section is a step-by-step tutorial which shows you how to use the front-panel menu. We recommend that you spend a few minutes with this tutorial to get comfortable with the structure and operation of the menu. Page 26 Chapter 2 Front-Panel Menu Operation A front-panel menu tutorial Menu Example 1 The following steps show you how to turn on the menu, move up and down between levels, move across the choices on each level, and turn off the menu.
In this example, you will enable the function generator to automatically recall the power-down state when power is turned on. Page 28 Chapter 2 Front-Panel Menu Operation A front-panel menu tutorial Menu Example 2 The following example shows how to use the recall menu feature as a shortcut to set the command back to its original setting. Shift 1 Use recall menu to return to the command. The following steps show you how to enter a number in the menu. For this example, you will set the number of cycles for the burst modulation mode.
In amplitude modulation , the amplitude of the carrier is varied by the amplitude of the modulating waveform. SINE For the modulating waveform, you can select a sine, square, triangle, ramp, noise, or arbitrary waveform.
For this example, you will modulate the carrier with a sine waveform. Notice that the annunciator flashes, indicating that the displayed percentage is the depth also called percent modulation. Repeat this step as needed. Notice that the annunciator flashes, indicating that the displayed parameter is for the mode. Also notice that the hop frequency is displayed with fewer digits than the carrier frequency.
You can output the burst at a rate determined by the internal rate generator or the signal level on the rear-panel Ext Trig terminal. Notice that the annunciator flashes, indicating that the displayed Burst parameter is for the burst mode. You can sweep up or down in frequency, and with either linear or logarithmic spacing. Notice that the annunciator flashes, indicating that the displayed parameter is for the sweep mode.
Enables single trigger and triggers the generator. The following steps show how to turn off the comma separator. Page 45 Features and Functions You will find that this chapter makes it easy to look up all the details about a particular feature of the function generator.
Whether you are operating the function generator from the front panel or over the remote interface, this chapter will be useful. Page Output Configuration Chapter 3 Features and Functions Output Configuration Output Configuration This section contains information to help you configure the function generator for outputting waveforms. You may never have to change some of the parameters discussed here, but they are provided to give you the flexibility you might need.
If you continued change to a function that is not allowed with the selected modulation, the modulation mode is turned off. The default frequency is 1 kHz for all functions. For example, if you output a 1 MHz sine wave and then change the function to triangle wave, the function generator will adjust the output to kHz the upper limit for triangle waves. Page Output Amplitude Chapter 3 Features and Functions Output Configuration Output Amplitude As shown below, the output amplitude range depends on the function currently selected and the output termination.
The default amplitude is mVpp into 50 ohms for all functions. Output Minimum Maximum Function Termination You can set the offset to a positive or negative number with the restrictions shown below. If the specified offset voltage is not valid, the function generator will automatically adjust it to the maximum dc voltage allowed with the present amplitude.
The function generator calculates the average of the data points and compares the average to zero volts. At power-on, the units for output amplitude are volts peak-to-peak. The default is Vpp. You can specify whether you are terminating the output into a 50 ohm load or an open circuit. Duty cycle is specified as a percentage and represents the amount of time per cycle that the square wave is high. All of the standard output functions except dc and noise have an associated sync signal. For certain applications where you may not want to output the sync signal, you can disable the SYNC terminal.
This enables you to recall the entire instrument configuration with a single command from the remote interface or with just a few key presses from the front panel. You can configure the function continued generator to automatically recall the power-down state when power is restored. In , the amplitude of the carrier is varied by the amplitude of the modulating waveform.
The function generator will accept an internal modulating signal, an external modulating signal, or both. The default is Sine. The default is Hz. The default is Both internal-external. In , the frequency of the carrier is varied by the amplitude of the modulating waveform.
The function generator will accept only an internal modulating signal no external source is available. The default is 1 kHz. The five built-in arbitrary waveforms can be output at a maximum of 5 MHz.
Page Burst Modulation Chapter 3 Features and Functions Burst Modulation Burst Modulation You can configure the function generator to output a waveform with a specified number of cycles, called a burst.
You can output the burst at a rate determined by the internal rate generator or an external signal applied to the rear-panel connector. Page Burst Trigger Source Chapter 3 Features and Functions Burst Modulation Burst Trigger Source In the triggered burst mode, the function generator outputs a waveform with the specified number of cycles burst count each time a trigger is received. After the specified number of cycles has been output, the function generator waits for the next trigger while outputting no signal zero volts or the dc offset level.
When the gate signal is true, the function generator outputs a continuous waveform. When you enable the burst mode, the previous modulation mode is turned off.
