Acquisition Modes
Mode | Sample (Normal), Envelope, and Average |
---|---|
Number of Sampling Modules Accommodated | Up to four dual-channel electrical; up to two optical sampling modules. (Both single- and dual-channel modules are appropriate for the two channels associated with the slot). |
Population of the Ch 1/Ch 2 large slot with any module other than one requiring power only displaces functionality of the Ch 1/Ch 2 small slot; population of the Ch 3/Ch 4 large slot with any module other than one requiring power only displaces functionality of the Ch 3/Ch 4 small slot. | |
Number of Simultaneously Acquired Inputs | Eight channels maximum. |
Acquisition Characteristics
Characteristic | Description |
---|---|
Vertical Systems | |
Rise Time/Bandwidth | Determined by the sampling modules used. |
Vertical Resolution | 14 bits over the sampling modules’ dynamic range. |
Horizontal System | |
Four timebase modes are available: | |
Triggered Phase Reference*10 Timebase Mode | Timing information extracted from a user-supplied or from clock recovery signal significantly improves timebase accuracy and jitter performance of the triggered acquisition. Horizontal position is referenced to the trigger signal as with a traditional timebase. |
Free Run Phase Reference*10 Timebase Mode | All timing is based on a phase reference signal; accuracy and jitter as above; no trigger is needed, and correspondingly there is no timing relation to trigger signal. |
Short-term optimized Sequential*11 Timebase Mode | Best short-delay performance for acquisitions without the external phase reference signal. |
Locked to 10 MHz Reference Sequential Timebase | Provides the best long-delay performance for acquisitions without the external phase reference signal. The Lock is selectable between Lock to Internal 10 MHz and Lock to External 10 MHz for highest frequency accuracy. |
Main and Magnification View Timebases | 100 fs/div to 5 ms/div in 1-2-5 sequence or 100 fs increments. |
Maximum Trigger Rate | 200 kHz; in Phase Reference mode: 50 kHz. |
Typical Acquisition Rate | 150 ks/s per channel (standard sequential timebase); 50 ks/s (Phase Reference modes). |
Time Interval Accuracy (Standard Timebase) and Timing Deviation (Phase Reference Modes) | |
Phase Reference Timebase: Triggered | Maximum timing deviation relative to phase reference signal: |
Horizontal position after trigger event: | |
>40 ns | 0.2% of phase reference signal period (typical) |
≤ 40 ns |
0.4% of phase reference signal period (typical) Note: The performance depends on stable clock supplied to the Phase Reference module. Performance under SSC is lower and depends on modulation shape. |
Phase Reference Timebase: Free Run | Maximum timing deviation relative to phase reference signal: 0.1% or better of phase reference signal period (typical) |
Sequential Timebase*11 | |
Time Interval Accuracy, Horizontal scale: | |
1 ps + 1% of interval. | |
≥21 ps/div | 8 ps + 0.1% of interval (Short-term optimized mode). |
8 ps + 0.01% of interval (Locked to 10 MHz mode). | |
Horizontal Deskew Range Available (Sequential Timebase Only) | -500 ps to +100 ns on any individual channel in 100 fs increments. |
DSA8200 Record Length |
20, 50, 100, 250, 500, 1000, 2000, or 4000 samples; Longer records available as follows: |
IConnect® | 1,000,000 points |
80SJNB Jitter, Noise, and BER Analysis Software | 3,200,000 points |
Waveform Databases | 4 independently accumulated waveform records of up to 4 G waveform points. Variable waveform database mode with true first-in first-out of 2000 waveforms available on each of 4 waveform databases. |
Magnification Views | In addition to the main timebase, the DSA8200 supports two magnification views. These magnifications are independently acquired using separate timebase settings which allow same or faster time/div than that of the main timebase. |
