Description
Specifications A-2
2mHz to 100 KHz
10 digits
0.1%
DC to 50 MHz
Automatic, triggered, gated or software command
Same as SYNC output.
Fixed at carrier frequency
Sample clock can be frequency modulated by arbitrary
waveforms that are downloaded by the user
User waveform, any shape, 10 to 10000 waveform points
1 mS/s to 2 MS/s
7 digits
0.1%
DC to 100 MHz
Automatic, triggered, gated or software command
Same as SYNC output.
Programmable for selected sample clock frequency
5Meg points per second
Current segment is sampled continuously. TTL low level
programs carrier sample clock, TTL high level programs
shifted sample clock frequency. Sample clock changes
coherently between frequencies. FSK operates on arbitrary
waveforms only.
50 S/s to 100 MS/s
Front panel Trigger input BNC. Low level = carrier sample
clock; High level = hop frequency
From 10 MHz to DC
Same as internal trigger range
Minimum 1 waveform cycle + 50 ns
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.
