Jitter :
305.175781 Sa/s (40/131072 MSa/s)
40.000000 MSa/s
Not Applicable. Attainable rates are
40/N MSa/s where N = 1,2,3, and all even
values up to 131072.
80 psec (typical rms)
Pertinent SCPI commands: [SOURce:]ROSCillator:SOURce INTernal2
[SOURce:]FREQuency2 subsystem
TRIGger:STARt:SOURce INTernal2
Frequency Agility: No
Recommendation: Use if 40 MSa/s is required, or for lowest
jitter at other sample rates.
Built-In Waveforms (using 42.94967296 MHz internal reference
oscillator); in each case the frequency resolution equals the minimum
frequency:
Sine Waves: 0.01 Hz to 10.73741824 MHz
Square Waves: 0.0025 Hz to 2.68435456 MHz (normal range);
Average Duty cycle is 49.9 to 50.1% ± 3 nsec.
0.005 Hz to 5.36870912 MHz (doubled range);
Average Duty cycle is 44% to 56% ± 3 nsec.
Using frequency generator #1, square waves
inherit the timing jitter characteristics given
above for frequency generator #1. The sample
period is
1
⁄
4
of the square wave period.
Triangles, Ramps: For the default setting of 100 points per cycle:
0.0001 Hz to 107.3741824 kHz (normal range)
0.0002 Hz to 214.7483648 kHz (doubled range)
Higher frequencies are possible with fewer than
100 points per cycle. Points per cycle can be
4 to 262144.
