Remote Measurement

14. Monitoring Network

Multiple XL2 Analyzers connect with USB Device Servers to
a network for online monitoring of noise or other signals. An
instance of the Projector Software may be started for each XL2
Analyzer, with all XL2 screens being simultaneously displayed
on the PC monitor. The Projector Software offers the control of
each XL2 Analyzer from your PC.

Please contact NTi Audio for application details.

15. Remote Measurement

The XL2 Analyzer offers an optional remote measurement func-
tion. This allows querying the XL2 measurement data online
via the USB interface. Thus customers may program their own
measurement application on the computer, e.g. for sound level
monitoring or automated measurement tasks. The supported
XL2 measurement functions are

Sound level meter and spectrum analyzer SLMeter/RTA

Audio analyzer RMS/THD+N

The commands are send in ASCII format through the virtual
COM port to the XL2 Audio and Acoustic Analyzer.

Example:

Command set send to XL2 Analyzer:
