Card Properties

Details about the card characteristics described in the following table are presented in the chapters about specific load modules.

Card Specifications
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:

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.
