06 | Keysight | Segmented Memory Acquisition for InfiniiVision Series Oscilloscopes - Data Sheet

Figures 4a and 4b show examples of

capturing 1,000 consecutive remote

and data frames with the ID code

by setting the trigger condition to

trigger on either remote or data

frames with this specific frame ID.

Now we can easily measure the

timing latency between each remote

transfer request frame with a frame

frame response with the same frame

ID. In this measurement example, the

latency between segment 4 (remote

frame) and segment 5 (data frame)

was 4.821 ms. Also note that although

not shown, the time-tag on the last

captured segment (segment 1,000)

was approximately 9.5 seconds.

Capturing this much time using

conventional oscilloscope acquisition

memory at this sample rate would

require 16 Megapoints of memory.

Figure 4a: Remote frame 07FHEX captured as segment 4 has a time-tag of 32.3199 ms.

Figure 4b: Data frame 07FHEX captured as segment 5 is time-tagged at 37.1359 ms indicating a latency

of 4.816 ms.
