Selection of DSCan speed.
The digital scan cannot be slowed down while it is running. Generated data can therefore be lost if they
are not collected fast enough at the remote control interface. The maximum data throughput at the
remote control interface can be fixed indirectly by setting the DSCan speed.
The NORMal setting corresponds to a medium speed at which with all probability all the results can be
transferred to an application via the Ethernet interface with the aid of TCP. This is the standard setting
after power-up of the unit and corresponds to the DSCan speed in firmware versions up to V02.22.
The LOW setting corresponds to a speed which is about 10 times less than that of the NORMal setting.
The maximum data rate is limited to 6 Kbyte/sec. This setting enables the transfer of all data via the
RS232 PPP interface with the aid of UDP.
The HIGH setting gives the highest speed. The data rate can be as much as 260 Kbyte/sec. The results
can be transferred to an application only via the Ethernet interface with the aid of UDP.
In position MTIMe it is not the hardware-supported sweep mechanism of the DSCAN which is used but
incremental frequency stepping as in F-SCAN. This permits level measurement to be carried out for
each channel in a specific measuring time. This mode is particularly suitable when it comes to measure
impulse noise and simultaneously indicate the spectrum on the display. The speed depends on the
measuring time.
