Overviews

This section contains the following overviews:

• “Dual Arbitrary Waveform Generator (Option UND)”

• “Multichannel, Multicarrier CDMA Personality (Option UN5)” on page 1-4

Specifications

Option specifications are included in the technical specifications document.

Dual Arbitrary Waveform Generator (Option UND)

Option UND enables you to drive the signal generator’s internal I/Q modulator to create vector-modulated signals. The Dual Arbitrary Waveform Generator uses 14-bit DACs for superior fidelity, as well as sampl e rates ranging from 1 Hz to 40 MHz, and 1 Megasample memory per channel.

The Dual Arbitrary Waveform Generator has a digital signal proces sor capable of simulating optional digital communication formats, such as the “Multichannel,

Multicarrier CDMA Personality (Option UN5)” described on page 1-4.

Alternately, you can use an external simulation (such as Omnisys) to generate the I/Q waveforms , do wnload them into th e I RAM and Q RAM, and s equence them for “pla yback. ”

Using simple table editors, you can save different waveforms as se parate segments, and subsequently sequence them to create a chain of repeating w aveform types. You can store this information to the signal generator’s internal memory and recall it as needed.

Dual Arbitrary Waveform Generator User’s and Programming Guide

ESG Family Signal Generators The Dual Arbitrary Waveform Generator Options UND & UN5 Overviews

Option UND also includes the following:

• Waveform triggering. Trigger types include continuous, single, gated, and (while using waveform sequence s) segme nt advance. The retrigger mode is ad justable , as well as the gate active trigger polarity for gated triggers. The trigger source can be set to the signal generator’s front panel trigger hardkey, the GPIB interface, or an external trigger signal supplied to the rear panel P ATTERN TRIG IN connector. External triggers include adjustable polarity, delay, and delay time.

• Waveform utilities: ❏ Markers, the signal generator has two markers, that you can place on a waveform

segment. Markers provide auxiliary output signals that are synchronized with a waveform segment. You can construct these output signals as a trigger signal to synchronize another instrument to a given portion of a waveform.

❏ Scaling to change the peak-to-peak output value of a wave form segment to a desired

percentage of its full-scale value.

❏ Baseband clipping to limit peaks in a waveform segment by clipping the envelope to

a desired percentage of the highest peak. You can clip the composite I/Q waveform or Iand Q separately.

• Additive White Gaussian Noise. AWGN can be used to crea te nois e signals with adjustable bandwidth, waveform length and noise seed (fixed or random).

• Multitone wa veforms. You can generate multitone wavefor ms with adjustable frequency spacing, frequency offset, power, phase, and tone on/off state.

• The Bluetooth wavef orm. You can generate packets (DH1) and impairments (ad justable frequency offset, frequency drift, modulation index, and AWGN).

• Other Formats. You can generate single carrier or multicarrier waveforms consisting of preconfigured or custom digital modulation formats:

❏ Triggering types include, s ingle, c ontinuous , or gated w aveform trigger ing , inc luding

retrigger mo de.

❏ Multicarrier wavefo rms with an adjust able number of car riers, frequency offset, and

power.

❏ Custom single carrier waveforms with configurable digital modulation type, filter,

and symbol rate.

The Dual Arbitrary Waveform Generator ESG Family Signal Generators Overviews Options UND & UN5

Multichannel, Multicarrier CDMA Personality (Option UN5)

Option UN5 provides multichannel, multicarrier IS-95 CDMA personality for amplifier characterization. This option requires Option UND.

Multichannel CDMA signal generation is simplified by the inclusion of 9-, 32-, and 64-channel pre-defined waveforms, offering precise signal statistics while optimizing measurement accuracy.

Multicarrier CDMA signal generation is simplified by the inclusion of 3- and 4-carrier pre-defined waveforms, offering precise signal statistics while optimi zi ng measurement accuracy.

Mobile component test is simplified using pre-defined Pilot and Reverse channel signals, and the ability to generate multiple pilot channels (Walsh 0, different PN offset) at equal or differing power levels. You can also generate a single reverse channel for mobile amplifier testing.

Option UN5 also allows for custom, user-defined multichannel and multicarrier CDMA signals. The multichannel capab ilities include the simulation of fully loaded cells by generating up to 256 Walsh-coded channels, as well as the ability to define power, PN offset, and data for each Walsh-coded channel. Multicarrier capabilities include the ability to generate multicarrier CDMA setups employing up to twelve carriers with individually defined multichannel configurations, frequency offsets, and power levels. Option UN5 also includes the ability to download or enter user-defined FIR filter coefficients.

Waveform triggering is included with Option UN5. Trigger types include continuous, single, and gated. The retrigger mode is adjustable, as well as the gate active trigger polarity for g a t ed tr i g g e rs. The tr i g ge r source can be se t to th e si g n a l ge n e ra t o r’s fron t panel trigger hardkey, the GPIB interface, or an external trigg er signal supplied to the rear panel PATTERN TRIG IN connector. External triggers include adjustable polarity, delay, and delay time.

The baseband clipping capability allows you to clip the composite I/Q w aveform or I and Q separately. You can also choose either pre- or post-FIR filter clipping.

Dual Arbitrary Waveform Generator User’s and Programming Guide 2-1

Using Functions ESG Family Signal Generators Table Editor Basics Options UND & UN5

Table Editor Ba si cs

Option UND provides several table editors that enable you to:

• edit a CDMA channel setup (for details, see page 2-4)

• edit a multicarrier CDMA setup (for details, see page 2-15)

• create a user-defined FIR filter (for details, see page 2-35)

• create multitone waveforms (for details, see page 2-47)

• build and edit waveform sequences (for details, see page 2-54)

• edit waveform segments (for details, see page 2-55) While each of these table editors performs a different function, they are all used in

basically the same way, and most of the table editors have several editing softkeys in common.

Common Edit Functions

Edit Item Enables you to use the front panel knob and arrow keys to edit the value of

a selected entry. After highlighting the value you want to edit, press this softkey.

Insert Row Inserts a row for data above the currently selected row. Delete Row Deletes the currently selected row of data. Goto Row Displays a new page of softkeys so that you can quickly move to the

first, middle, or last row of data. This is especially helpful in a large table, or when using the filter table editor mirror function.

ESG Family Signal Generators Using Functions Options UND & UN5 Creating Custom CDMA States

Creating Custom CDMA States

Using this procedure, you will create a custom, forward 33 channel CDMA signal at IS-97 power levels with a traffic channel carrying user-defined data at a Walsh code of 45.

The signal generator provides a quick and easy solution to cre ating custom CDMA states. Rather than building the entire 33 channel set up from scratch, you will start with a forward 32 channel CDMA template and modify the template by adding one channel and changing some of the template’s default values. (Options UND and UN5 are both required.)

Setting up a CDMA Template

The first step in creating a customized CDMA state is setting up a template that can be modified to fill your requirements. Follow these steps to set up a forward 32 channel CDMA template:

1. Preset the signal generator to normal preset conditions.

2. Press the front panel

Mode key.

3. If you have multiple options and the next.

4. Press Press

CDMA Formats > IS-95A > Setup Select. The default CDMA template is set to 9 Ch Fwd. 32 Ch Fwd. This sets up a template containing 32 forward CDMA channels.

Creating a Multitone Waveform

The following example walks you through creating and storing a simple 5-tone waveform. You can use this example to familiarize yourself with the various parameters that are available to customize this type of waveform.

Initialize the Multitone Table Editor

The first step in creating a multitone waveform is to set the number of tones and the frequency spacing between those tones . This is termed initializing t he table editor, because this is the only way to set the frequencies and number of tones, and when you change either the number of tones or the freque ncy spacing, the relative power level of all tone s is set to 0.00 dB, the phase of all tones is set to zero, and all tones are turned on.

1. Preset the signal generator, then press

Multitone. The signal generator displays the multitone table editor, which will look

(5 in this example), but the number of tones in the table editor has not changed.

4. Press

Freq Spacing.

Tones are evenly spaced about zero. When there are an even number of tones defined (as shown in the previous figure), the center two tones are placed on either side of zero. For an odd number of tones (as you specified in step 3), the center tone is placed at zero.

Also, if you set the frequency spacing less than approximately 5 kHz, the ALC can interact with the tones, causing some distortions as evidenced by intermodulation products outside the desired tones. To eliminate this effect, turn off the ALC.

5. Using the front panel number keys , enter

20, then press the kHz softkey to terminate the

entry.

Building a Waveform Sequence

Follow the guidelines in this section to learn how to build waveform sequences from waveform segments using the d ual ar bitrary w a vefor m generat or. (Options UND and UN5 are both required.)

In this example, you will generate two different types of CDMA waveform segments, a 64 channel forward and a 9 channel forward signal. After you have the two waveform segments stored in NVARB memory, you will build a sequence using each one of these waveform segments.

NOTE There are two kinds of arbitrary waveform generat or me mory : ARB memory

and NVARB memory. ARB memory is volatile. Data held in ARB memory is destroyed if the signal

generator’s line power is cycled. NVARB memory is non-volatile. Data held in NVARB memory is not

destroyed if the signal generator’s line power is cycled. For more information on ARB and NVARB memory, see “Managing Volatile

and Non-Volatile ARB Memory” on page 4-4.

Generating the First Waveform

There are two ways to provide waveforms for use by the sequencing and playback sections of the signal generator. You can either download a waveform via GPIB or generate a waveform in a CDMA format. For information on downloading waveforms via GPIB, see

“Downloading Waveform F iles Into Memory” on page 2-72. The following procedure shows

how you can generate a waveform using the IS-95A CDMA (Option UN5) format. For information on generating waveforms using other CDMA formats, refer to the user’s and programming guide for the specific CDMA format option.

Using Markers

The signal generator has two markers that you can place o n a w aveform s egment; markers provide auxiliary output signals that are synchronized with a w aveform segment. You can construct these output signals as a trigger signal to synchronize another instrument to a given portion of a waveform.

In some situations, it can be useful to use the markers to generate a clock signal. Using a CDMA waveform as a waveform segment (an ARB sample clock frequency is a multiple of the chip rate. Using markers and the #Skipped Points feature, you can construct a clock at the chip rate easily.

Using Functions ESG Family Signal Generators Scaling Waveform Segments Options UND & UN5

Scaling Waveform Segments

The scaling feature can be used to scale waveform segments. It scales the waveform segments by changing the peak-to-peak output value of the selected waveform segment to a desired percentage of its full-scale value. Scaling has two purposes. First, scaling can be used to reduce the distortion that may be present with the waveform set at its full scale. Scaling can also be used to scale I and Q rear panel output levels of IS-95A signals generated by Option UN5. By setting scaling for the AUTOGEN_WAVEFORM waveform, you can change th e I and Q signals from the def ault value . A w avef orm segment must be selected in the volatile ARB waveform memory befor e it can be scaled. The scaling can be set from 1 to 100% in 0.01% increments.

NOTE The output of the Dual ARB waveform is determined by the least significant

14 bits of a 2-byte integer (see “Waveform Composition” on page 4-6). As the waveform is scaled down, it can lose bits of resolution. Once a bit of resolution is lost, it can not be regained by increasing the scaling value of the waveform.

Downloading Waveform Files Into Memory

Follow the guidelines in this section to learn how to download waveform files into the signal generator’s ARB memory. (Option UND is required.) For inf ormation on system interface, including GPIB and RS-232, refer to the programming guide.

Downloading Waveform Files Into ARB Memory

Downloading waveforms into volatile (ARB) memory is much quicker than downloading waveforms into non-volatile (NVARB) memory. If you want to store waveforms in NVARB memory, first follow the instructions to download into volatile ARB memory and then copy or move the waveforms internally into NVARB memory. See the following section titled, “Transferring Waveforms Between ARB and NVARB Memory.”

Use the following SCPI command lines to download a waveform to ARB memory:

MMEM:DATA "ARBI:<waveform_name>",<I_waveform_data>

This command downloads the I values for your waveform. The variable <waveform_name> denotes the name that will be associated with the downloaded waveform data within the signal generator and therefore must be the same for both I and Q downloads.

MMEM:DATA "ARBQ:<waveform_name>",<Q_waveform_data>

This command downloads the Q values for your waveform. The signal generator will associate t he I w a vefor m val ues and the Q w a vefo rm values, and

drive the I and Q modulators with the stored waveform in the baseband generator. If only one of the two required c ommands is execut ed (I valu es only o r Q val ues only), the missing data will be set to values corresponding to a 0 V output.

Sample Command Line

This command selects the waveform called

<waveform_name> in ARB memory as the

modulation for the signal generator’s RF output.

:RADio:ARB:WAVeform "SEQ:"<sequence_name>""

This command selects the user- defined sequence from the signal generator’s catalog memory as the modulation at the signal generator’s RF output.

This command drives the I and Q modulators with the chosen waveform/sequence in the baseband generator.

NOTE If you attempt to stop sending information to the signal generator duri ng th e

execution of a remote command that is sending waveform data, the signal generator will wait indefinitely for further input.

If this happens , you should execute the app ropriat e d evice c lear command for your programming language over GPIB.

As an example, in BASIC this command is

ESG Family Signal Generators Using Functions Options UND & UN5 Using Arbitrary Waveform Generator Triggers

Using Arbitrary Waveform Generator Triggers

The arbitrary waveform generator includes several different triggering options. For information on the triggering capabilities of the signal generator, see “Understanding

Arbitrary Waveform Generator Triggers” on page 4-8.

NOTE Dual ARB triggers and their associated softkeys and SCPI functionality

became available in signal generators with serial number prefix US3844 or GB3845. Dual ARB triggers are not available in signal generators with an earlier serial number prefix, unless upgraded.

To upgrade your signal generat or to include Dual ARB triggering, contact your nearest Agilent Technologies Sales and Service office.

In the following procedures, you will learn how to create a time-delayed, externally triggered custom multicarrier CDMA wavef orm (“Creating an Externally Triggered

Custom Multicarrier CDMA Waveform” on page 2-81) and how to use segment advance

triggering with waveform sequences (“Controlling Waveform Sequence Playback Using

Segment Advance Triggering” on page 2-86).

Creating an Externally Triggered Custom Multicarrier CDMA Waveform

Using this procedure, you will recall a custom multicarrier CDMA state from the signal generator’s MCDMA memory catalog and single-trigger the waveform externally with a 100 msec delay.

For this example, re c all procedure titled, “Creating Custom Multicarrier CDMA Waveforms” on page 2-15 and stored using the procedure titled, “Storing a Custom Multicarrier CDMA Waveform” on page 2-23. If you have not created and stored a custom multicarrier CDMA waveform, refer to the se previous sections. (Options UND and UN5 are both required.)
