User Manual PXA125
Specifications A-96
Memory Interleave 4 (All trace lengths must be multiples of 4)
Vertical Resolution 14 bits (16,384 points)
Waveform Download Rate 5 Meg points per second
Sine Wave Performance
Description Sine wave performance is measured using the maximum sample clock rate,
at 5 Vp-p, the maximum amplitude resolution of the DAC (14-bit) and without filters. Spectrum ana-
lyzer settings: Start frequency = 0 MHz; stop frequency = 50 MHz (Nyquist frequency)
Sinewave Total Harmonic Distortion 0.05% to 100 KHz
Harmonics and non-related spurious < -55dBc for carrier frequencies ≤ 1MHz
< -40dBc for carrier frequencies ≤ 5MHz
< -35dBc for carrier frequencies ≤ 10MHz
< -22dBc for carrier frequencies ≤ 50MHz
SEQUENCED ARBITRARY WAVEFORMS
Operation Permits division of the memory bank into smaller segments. Segments may
be linked, and repeated in user-selectable fashion to generate extremely long waveforms.
Advance Modes
Automatic Sequence Advance No triggers required to step from one segment to the
next. Sequence is repeated continuously through a pre-programmed sequence list (table)
Stepped Sequence Advance Current segment is sampled continuously, external
trigger advances to next programmed segment. Control input is TRIG IN connector.
Single Sequence Advance Current segment is sampled to the end of the seg-
ment including repeats and idles there. Next trigger advances to next segment. Control input is TRIG
IN connector.
Mixed Sequence Advance Each step of a sequence can be programmed to ad-
vance either a) automatically (Automatic Sequence Advance), or b) with a trigger (Stepped Sequence
Advance)
Advance Source External, Internal, or soft trigger
Sequencer steps From 1 to 4096
Segment loops From 1 to 128 K
