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 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
