Card Properties
Details about the card characteristics described in the following table are presented in the chapters about specific load modules.
Specification | Usage |
---|---|
# ports |
The number of ports supported by the card(s). |
-3/-M/L Card Available |
Whether a limited feature card is available. |
L2/L3 Card Available |
Whether a Layer 2/3 only card is available. |
Layer 7 Card Available |
Whether a Layer 7 only card is available. |
Data Rate |
The choice of data rates offered by the card. |
Connector/Frequency-Mode |
The connector type used on the card. For optical connections, the light frequency used and whether the fiber is used for singlemode or multimode. |
Capture buffer size |
The size of each port's capture buffer. |
Captured packet size |
The range of packet sizes that may be captured on the card. |
Streams per port |
The number of streams available on each port. |
Flows per port |
The number of stream flows available on each port. If available, this is always 15,872. |
Advanced streams |
The number of advanced streams available on each port. |
Preamble size: min-max |
The range of sizes, in bytes, for generated preambles. |
Frame size: min-max |
The range of sizes, in bytes, for generated frames. |
Inter-frame gap: min-max |
The gap between frames, expressed as a range of time. |
Inter-burst gap: min-max |
The gap between bursts of frames, expressed as a range of time. |
Inter-stream gap: min-max |
The gap between streams, expressed as a range of time. Sometimes expressed as a percentage of the maximum rate. |
Latency |
The accuracy of latency operations. |
Intrinsic Latency Adjustment |
Reduce the measured latency by the amount of latency that is induced by the test equipment itself (not the DUT). Retrieves pre-determined latency value for a `known' transceiver, or calculates and stores that value for a `new' transceiver. |
Number of captured packets, an important characteristic, cannot be expressed as a simple number. It is dependent on a number of factors as mentioned in the following list:
- Size of the capture buffer
- Size of the captured packet
- Size of the capture slice, set by you
- Memory used by other functions
- Memory overhead per captured packet
The general equation is:
# of captured packets = (size of capture buffer) - (memory used by other functions) (min (captured packet, capture slice) + (per packet overhead)
Maximum number of PGIDs
The maximum number of PGIDs for designated load module families is provided in the following table.

Latency/Jitter |
|
1The maximum number of PGIDs is the maximum hardware PGID that can be supported by a particular load module in a particular mode. If time bin, latency, or other parameters are enabled, the maximum PGID that can be supported is reduced. All modules have a maximum 2048 time bins. All modules that support latency bins have quantity 16 latency bins.
