E&OE

[1]	Supports 4 different generator types: VSR = Variable Sample Rate, DDS = Direct Digital Synthesis, CLK = Clock Generator, PRNG = Psuedo Random Number Generator.
[2]	Minimum and maximum frequency depends on generator type as indicated.
[3]	Uncalibrated frequency accuracy is specified (as defined by the BS100U reference crystal). May be calibrated to better than this if precision frequency reference is available.
[4]	Temperature Coefficient is that of the BS100U reference crystal.
[5]	Trigger, Burst and Clock modes may be configured to accept or generate a trigger or clock signal via the TimePort.
[6]	The maximum duration or delay depends on the sample rate. The maximum duration in all cases exceeds 1 hour but can extend far beyond this limit at lower sample rates.
