Taking Measurements - Promax PROLINK-4/4C Premium Manual De Instrucciones

USER'S MANUAL. PROLINK-4/4C
To activate rows where you wish to store measurements use key
place the cursor on the rows field, then turn the rotary selector [4] until it is over the row
you want to activate and press the rotary selector [4]. The activated rows are more
brilliant than the non activated ones. To deactivate a row follow the same steps as in
activating it. In the case of activating more than one row, the time interval between the
measurement of each row is determined by the Measure interval parameter defined in
the configuration screen (1 minute by default).
By means of the Acquisition function it is possible to carry out the measurements
referred to the most characteristic digital signal parameters: BER or MER for QAM
modulations; BER, CSI or MER for COFDM and MER, VBER (BER after Viterbi) or
CBER (BER before Viterbi) for QPSK and DAB signals; CBER (Coded BER) and SNR.
(see section '4.12.1 Storing a Measurement Configuration (STORE) ').

4.9.4.4.3 Taking Measurements

In addition to execution by alarm (see section '4.9.4.4.1 Configuring the
Datalogger Function') there are three more ways to take measurements:
a) Acquisition over a time period of a measurement
The measurement defined in a memory (column) will be taken as many times
as there are activated rows, as specified by the time interval between
measurements defined in the configuration menu (Measure interval).
Process: place the cursor on the column you want and press the rotary
selector [4] until the first active cell is highlighted. If no measurement matrix
row has been previously activated, the bottom of the screen will show the
error message "NOT CELLS SEL." (No cells selected).
b) Acquisition of different measurements at the same moment.
Multiple measurements in a row will be taken, as specified by the
measurement configurations defined in all the activated columns.
