Spirent TestCenter: Do we support latency values in Latency-Jitter Mode for Detailed Streams results view?
What counter mode supports Latency and Jitter counters at the same time?
All test modules
Latency with RFC 5481 Jitter Mode
Latency - Jitter
On the older modules like CV-10G-S and MX-10G-S we have the original Latency-Jitter Mode. For these modules we supported latency, jitter and dropped frame count in this mode.
new counter mode:
Latency with RFC 5481 Jitter Mode was introduced in
release that allows latency and jitter to be collected concurrently per stream
for Spirent FX3/MX3, 400G Appliance and 400G Modules
Since the newer modules FX3/FX2 and MX3/MX2 were designed for higher stream counts. The trade-off was a smaller number of counters for each counter mode, that was the initiall reason the first counter (Latency-Jitter mode) isn't showing Lattency and Jitter on the same view)
Other modules like DX2 and MX2 still doesn't support Latency and jitter to be collected concurrently.
Please refer to KB:

So you can validate by yourself the counters supported by each test module
