|The 41-620 is a compact 3 channel function generator
provided in a PXI 3U single slot module. It is capable of
generating sine waves to 10MHz with 48-bit frequency
resolution referenced to the 10MHz PXI clock or to an
external standard. The 41-620 can generate arbitrary
waveforms loaded into the internal 256k memory, allowing
the function generator to emulate many waveform types,
including the typical waveforms of automotive and aerospace
sensors.The function generator provides a very simple method of
providing variable output frequencies through the use of
Direct Digital Synthesis (DDS), making it far easier to use than
an ARB for repetitive waveform generation.The 41-620 is capable of generating fast swept frequency
signals, permitting the output to emulate the operation of
variable speed devices. Sweeps can be single shot events or
continuous up and down ramps. The DDS technology ensures
the 41-620 settling time is extremely fast, being limited only
by the update time over the PXI bus.The 41-620 supports the PXI Trigger functions to allow triggered events from other instruments to initiate waveform generation or sweeps.
