ATS850 User Manual 45
Dynamic Parameters
Typical values measured using a randomly selected ATS850 in
±
1V input
range, DC coupling and 50
Ω
impedance. Input was provided by a HP8656A
signal generator, followed by a 9-pole, 1 MHz band-pass filter. Input
frequency was set at 1 MHz and amplitude was 650 mV rms (92% of full
scale input).
SNR 42 dB
SINAD 40 dB
THD -46 dB
SFDR -45 dB
Note that these dynamic parameters may vary from one unit to another, with
input frequency and with the full-scale input range selected.
Optional ECLK (External Clock) Input
Signal Level TTL levels. Compatible with both 3.3V and 5V
TTL
Input impedance 50
Ω
Input current requirement ± 66mA
Maximum frequency 50 MHz with 50%
±
5% duty cycle
Minimum frequency 10 KHz with 50%
±
5% duty cycle
Decimation factor Software selectable from 1 to 100,000
Sampling Edge Rising or Falling, software selectable
Triggering System
Mode Edge triggering with fixed hysteresis
Number of Trigger Engines 2
Trigger Engine Combination OR, AND, XOR, software selectable
Trigger Engine Source
CH A, CH B, EXT, Software or None,
independently software selectable for each of
the two Trigger Engines
Hysteresis ± 5% of full-scale input, typical
Trigger sensitivity ± 10% of full scale input range.
This implies that the trigger system may not
trigger reliably if the input has an amplitude
less than
±
10% of full-scale input range
selected
Trigger level accuracy
±10
%, typical, of full-scale input range of the
selected trigger source
Bandwidth 25 MHz
Trigger Delay Software selectable from 0 to 9,999,999
sampling clock cycles
Trigger Timeout Software selectable with a 10 us resolution.
Maximum settable value is 3,600 seconds.
Can also be disabled to wait indefinitely for a
trigger event
