DUAL 100MSPS ARBITRARY WAVEFORM GENERATOR CARD
pickering
SECTION 1 - INTRODUCTION & INSTALLATION
Introduction
The 41-610 is a dual-channel PXI-based Arbitrary Waveform Generator.(AWG or ARB) using a 14-bit high speed
digital to analog converter. Figure 1-1 shows the functional block diagram from the 41-610.
Channel-B is an exact copy of channel-A except for the addition in the signal path to Channel-A that permits the
two channels to be combined (B channel inverted) and routed to the Channel A output connector.
On the left of the diagram is the PXI interface from the chassis backplane.
The core of the ARB contains an address counter and a 14bit x 512k RAM memory, the memory output being
supplied to a 14 bit DAC system.
When the 41-610 is triggered, the memory contents are read out, starting from a user defined start address.
While the ARB is running an internal or external clock increments the memory counter. When the counter reaches
the value of the stop address it jumps back to the start address to allow the generation of continues analog pat-
terns.
If desired the generated analog signal can be filtered to remove broadband signals when operated at lower fre-
quencies.
The output level is adjusted by two controls, an attenuator and Dc reference voltage. The attenuator has 7 steps
of 3dB each. Fine control is managed by the DAC programmable reference voltage that allows a proportional
output level variation of 3 dB. The reference voltage to the DAC can be adjusted over a larger range, but may
impact the performance of the converter. The 7 of 3 dB steps and and the 3 dB adjustment of the reference volt-
age provides a total voltage range of 24 dB. The output voltage range can be reduced further using the reference
voltage.
A DC-offset voltage can be added to the signal. The outputs for both channels use differential 50 Ohm amplifiers,
the differential signals appearing on two outputs for each channel.
