User Manual PXA125
Specifications A-93
Output and Level Same as SYNC output.
Position Programmable for selected sample clock frequency
Waveform Download Rate 5 Meg points per second
FSK
Description Current segment is sampled continuously. TTL low-level programs carrier
sample clock, TTL high level programs shifted sample clock frequency. Sample clock changes co-
herently between frequencies. FSK operates on arbitrary waveforms only.
Carrier Sample Clock Range 100 mS/s to 125 MS/s
FSK Stimuli
External Front-panel Trigger input BNC. Low level = carrier sample clock;
High level = hop frequency
Frequency Range From 10 MHz to DC
Internal Same as internal trigger range
FSK Delay Minimum 1 waveform cycle + 50 ns
Ramped FSK
Description Same as FSK except carrier sample clock ramps to shifted frequency at a
rate defined by the ramp time parameter. TTL low-level programs carrier sample clock, TTL high level
programs shifted frequency.
Ramp Time Range 10

Sweep
Description Sample Clock sweeps continuously from start to stop, at a rate defined by
the sweep time. More complex sweep modes and types can be generated using the FM mode in
conjunction with the FM composer program.
Type Linear or logarithmic
Direction Up or down, depending on the start and stop setting
Range 100 mS/s to 125 MS/s
Time 1 ms to 1000 s, 7 digits,
