DATA LOGGER
The instrument’s Data Logger allows for measurements to be performed and for the results
to be stored in the system’s memory. The stored data can then be accessed by means of
the system's display, as well as through the RS232 serial port.
For each entry, in addition to the frequency and channel, the following elements can also be
saved:
for analogue signal measurements: level, V/A, C/N.
for digital signal measurements: POW, C/N, BER, MER, NM.
Following acquisition, all of the data can be cleared simultaneously
The Data Logger’s structure allows for the acquisition of analogue and/or digital program
measurements, up to a maximum of 50 programs for each of the five acquisition plans.
If “OPT” mode is selected for the plan in use, in addition to the optical measurements, the
RF measurements deriving from the optical / RF conversion will also be saved.
Press the
DATA
button for about two seconds to enable the use of the Data Logger.
