• Version will be ADS 2003C, available in Dec 2003

• Prototype available, please contact your application engineer


Record and Playback Long WaveformsTake your waveform simulation to the next level…• Record signals off the air with the 89600 VSA

• Transfer files to a PC equipped with Baseband Studio and re-format

• Stream them into the PSG or ESG signal generator for playback

What Problems Does It Solve?Problem 1Digital devices need to be tested with meaningful “real-world” signals

Why?• Digitization in Communications systems• Digitization in Aerospace/Defense designs• Using the same signals at RF and baseband (digital) reduces errors

SolutionSolution

Digital Bus DUTPSG (to 20 GHz)

Target applications (R&D)• Transceivers• Components (DAC, DSP, FPGA…) • BTS subsystems (cards, slots,

modems…)• Mobile stations• MCPA digital pre-distortion• Antenna systems • Software Definable RadioESG (to 6 GHz)

Digital I/Q


What problem does it solve?Problem 2Every new project requires custom built converters

Why?• Every new project brings new demands for data, clock and interfaces• Waveform generators offer only one type of data format, electrical

interface and connector

SolutionSolution

Breakout boards (included): allow direct DUT connection

3 meter cable: place module next to DUT

• Multiple data formats• Multiple logic types (LVDS, TTL, CMOS…) • Perfect resampling• Highly-requested clock features

How the Digital Signal Interface Module Works Clock source and frequency reference options

ESG/PSG module DUT

(a) The DUT supplies the clock. RULE:

The host (ESG/PSG)

must always lock to the

source of the clock.

(b) The module supplies the clock.

(b) An external clock source supplies the clock.

How the Digital Signal Interface Module Works Clock-to-data skewPurpose: to meet sample and hold criteria of device Function: built-in clock adjustment for aligning the clock edges to the valid

portion of dataExample

Data

Original clock

Shift by 180ºSkew (fine adjust)


How the Digital Signal Interface Module Works Multiple clock cycles per sample

• Purpose• When some devices on a customer’s board run at a clock rate that is a multiple

of the data rate• Function• Clock out the data samples at one rate, and provide the clock output at a higher

rate (x2 or x4)• Example

4 clock cycles/sample

1 sample
