Pulse and Pulse Train
Output level: 2.5 mV to 10V p-p into 50 Ω
Rise and fall times: <8 ns
Period:
range:
resolution:
accuracy:
40 ns to 100 s
8 digits
10 ppm for 1 year
Delay:
range:
resolution:
−99·99 s to +99·99 s
0·001 % of period or 10 ns, whichever is greater (8 digits)
Width:
range:
resolution:
10 ns to 99·99 s
0·001 % of period or 10 ns, whichever is greater (8 digits)
Note that the pulse width and absolute value of the delay may not exceed the pulse period
at any time.
Pulse trains of up to 10 pulses may be specified, each pulse having independently defined
width, delay and level. The baseline voltage is separately defined and the sequence
repetition rate is set by the pulse train period.
Arbitrary Waveforms
Up to 500 user defined waveforms may be stored on the removable memory card.
Waveforms can be defined by front panel editing controls, by downloading of waveform
data via RS232, GPIB or USB, or by writing directly to the removable memory card
using the USB card reader/writer connected to a PC.
Waveform memory size: 1 M points per channel.
Minimum waveform size is 8 points
Vertical resolution: 12 bits
Sample clock range:
resolution:
accuracy:
100 mHz to 100 MHz
8 digits
10 ppm for 1 year
Sequence
Up to 1024 waveforms may be linked. Each waveform can have a loop count of up to
32,768.
A sequence of waveforms can be looped up to 1,048,575 times or run continuously.
Output Filter
Selectable between 40 MHz elliptic, 20 MHz Bessel or none.
Noise
Digital noise generated by a 35-bit linear feedback register clocked at 100 MHz. User’s
external filter defines bandwidth and response.
