Step 2: Setting stream control

The interval gap of the frame set in step 1 is set and the data stream

is defined. Commonly, an actual network load is not a stationary

load but a burst load. To simulate this type of load, the MD1230A

has a multi-burst function. In addition, a random frame interval can

be simulated by setting to random within a specified packet interval

range.

•

Compact and lightweight unit with built-in Windows

98 OS

For easy and familiar operability, the MD1230A uses the built-in

Windows

98. In addition, it also has a USB port for connecting a print-

er or external storage media. A PS/2 keyboard connector and USB

connector on the front panel support connection of a keyboard and

USB mouse. The MD1230A’s easy operability, compact size and light-

weight offer the perfect solution for convenient on-site troubleshooting.

•

Remote control from PC

When the MX123001A Data Quality Analyzer Control Software (sold

separately) is installed in a PC running Windows

98, up to eight

MD1230A units can be controlled via a network.

•

Automated measurement using GPIB commands (Option)

Almost all the MD1230A functions can be executed by GPIB com-

mands. An automated test system can be configured by operating

the MD1230A from the user's application software. In addition, the in-

terface for sending and receiving GPIB commands can be selected

from any of the optional GPIB (MD1230A Option 02), RS-232C

(MD1230A Option 01) and Ethernet (MD1230A Option 03) interfaces.
