Quick Start

This manual contains supplemental information for the Agilent 33120A Phase-Lock assembly. Refer to the 33120A User’s Guide and Service Guide for complete details on using the function generator.

The Phase-Lock assembly (Option 001) adds the following capabilities to the 33120A Function / Arbitrary Waveform Generator:

 External clock input and output connectors on the rear panel.

These connectors allow synchronization between multiple 33120As or to an external 10 MHz clock signal.

 Phase offset control from the front panel or over the remote interface.

 Simultaneous hardware triggering of multiple Agilent 33120As.

Option 001 allows the 33120A to generate a trigger pulse from the Ext Trig terminal which can be routed to other instruments in a system.

 2 ppm timebase—10 times the frequency stability of the standard

Agilent 33120A.

If you have questions relating to the operation of the function generator, call

1-800-452-4844 in the United States, or contact your nearest

Agilent Technologies Sales Office.

The Front-Panel Menu at a Glance

The Phase-Lock assembly adds the Phase Menu to the front-panel menu.

The menu is organized in a top-down tree structure with three levels.

G: PHASE MENU

1: ADJUST Õ 2: SET ZERO Õ 3: TRIG OUT Õ 4: UNLOCK ERR

1: ADJUST 2: SET ZERO 3: TRIG OUT 4: UNLOCK ERR

Sets the phase offset of the output waveform to a value in degrees. Nulls the phase offset to a zero reference for relative adjustments. Enables or disables an external trigger from the Ext Trig terminal. Enables or disables error generation when phase-lock is lost.

Chapter 1 Quick Start

To phase lock to an external clock signal

The rear-panel Ext Ref In terminal allows you to synchronize one or more function generators with an external 10 MHz signal. The following steps show you how to configure a single instrument for synchronization with an external signal.

Chapter 1 Quick Start

To phase lock multiple function generators

The rear-panel Ref Out and Ext Ref In terminals allow you to synchronize multiple function generators. The diagram below shows how to make connections for the “real-time” phase-lock mode. In the real-time mode, the phase offset relationship is random at first. You can adjust the phase offset “real time” from the front panel. The following steps show you how to synchronize two function generators at 10 kHz.

Freq

1 Set both instruments to the same output frequency.

You can select sine, square, ramp, or triangle waveforms for phase-lock operation. You cannot perform real-time phase adjustments on arbitrary waveforms.

Chapter 1 Quick Start

To phase lock using the triggered burst mode

The rear-panel Ref Out and Ext Ref In terminals allow you to synchronize multiple function generators. The diagram below shows how to make connections for the “triggered burst” phase-lock mode. In the triggered burst mode, you can synchronize phase-lock signals using an external trigger from the rear-panel Ext Trig terminal. The following steps show you how to synchronize two function generators at 10 kHz in the triggered burst mode.

This section summarizes the SCPI (Standard Commands for Programmable Instruments) commands available to program the Phase-Lock assembly over the remote interface. If you are a first-time user of the Language,” starting on page 211 in the 33120A User’s Guide.

Throughout this manual, the following conventions are used for

SCPI command syntax.

• Square brackets ( [ ] ) indicate optional keywords or parameters.

• Braces ( { } ) enclose parameters within a command string.

• Triangle brackets ( < > ) indicate that you must substitute a value

for the enclosed parameter.

• A vertical bar (

SCPI language, refer to “An Introduction to the SCPI

) separates multiple parameter choices.

Phase-Lock Commands

This section describes the SCPI (Standard Commands for Programmable Instruments) commands available to program the Phase-Lock assembly. Refer to chapter 4 in the 33120A complete set of commands for the function generator.

User’s Guide for details on the

PHASe:ADJust {<

Adjust the phase offset of the output waveform in radians. Select from

-2

π radians to +2π radians. The default is 0 radians. MIN = -2π radians.

MAX = +2π radians. [ Stored in volatile memory ]

• To specify phase in degrees instead of radians, specify “DEG” following

the phase value as shown below:

"PHAS:ADJ -90 DEG"

• For sine, square, triangle, and ramp waveforms, 0 radians is the point

at which the waveform crosses zero volts (or the dc offset value), in a positive-going direction. For arbitrary waveforms, 0 radians is the first point downloaded to memory.

• This phase adjustment for phase-lock is independent of the burst

phase as set by the BM:PHAS command. See “Burst Modulation” in the 33120A User’s Guide for more information on burst phase.

PHASe:ADJust?

Query the phase offset setting. Returns a value in radians.

PHASe:REFerence

Immediately set the zero-phase reference point. This command does not change the phase offset as set with the PHAS:ADJ command, it only changes the phase reference. This command has no query form.

Simplified Programming Overview

This section gives an overview of the basic techniques used to program the Phase-Lock assembly over the remote interface. This section is only an overview and does not give all of the details you will need to write your own application programs. Refer to chapter 6, “Application Programs,” in the 33120A User’s Guide for more details and examples. Also refer to the programming reference manual that came with your computer for details on outputting command strings and entering data.

Chapter 2 Remote Interface Operation

The SCPI Status Registers

The function generator uses the Status Byte, the Standard Event, and the Questionable Data register groups (phase-lock assembly only) to record various instrument conditions. This section discusses only the

Questionable Data register group; refer to chapter 4 in the 33120A User’s Guide for a complete discussion of the status registers. A diagram

of the

SCPI status system is shown on the next page.

An example program is included in chapter 6, “Application Programs,” of the 33120A User’s Guide which shows the use of the status registers. You may find it useful to refer to the program after reading the following section in this chapter.

Phase-Lock Error Messages

This section lists the two error messages that can be generated if the Phase-Lock option is installed. Refer to chapter 5 in the 33120A User’s Guide for a complete listing of error messages.

-221 Settings conflict; cannot adjust phase in present configuration

Option 001 Phase-Lock Only. The phase cannot be adjusted real-time if an arbitrary waveform is selected, a modulation mode (other that burst) is enabled, or if burst is enabled with a burst count other than infinity.

580 Phase-locked loop is unlocked

Option 001 Phase-Lock Only. The function generator has detected an “unlock” condition. You must execute the PHAS:UNL:ERR:STAT ON command to enable this error.
