SAMPLE CLOCK MODULATION
FM – Built-in Standard Waveforms
Description
Modulation Source
1
Multiple instruments can be connected together and
synchronized to provide multi-channel synchronization.
From Master card to slave boards through the local bus
Same as Sample Clock but limited to 80 Ms/s
<15 ns to the first master; 15 ns cumulative to additional
slaves
50 S/s to 100 MS/s
10 digits limited by 1 µHz
Same as reference
Same as reference
System clock, ≥0.01% (100 ppm)
≥0.0001% (1 ppm TCXO) initial tolerance over a 19°C to
29°C temperature range; 1ppm/°C below 19°C and above
29°C; 1ppm/year aging rate
10 MHz TTL, 50% ±2% duty cycle
Sample clock can be frequency modulated by internal
waveforms that are resident in internal memory (fixed
waveforms).
Internal sine, square, triangle and ramp
