12. Signal Analyzer & Generator
This item allows the selection of some measurement functions to test the
transmission performance of lines, apparatus and communication systems.
GENERATOR & METER:
Sinusoidal Signal Generator, wide or weighed band and Selective Level Meter up to 20
kHz, Selective Level Meter for medium/high band up to 6 MHz (or 35 MHz by internal
optional module), selective or wide band Frequency-Meter.
It allows these measurements to be performed:
- Insertion Loss (at a single frequency with two instruments);
- Noise (wide and weighed on base band);
- Crosstalk (NEXT with single instrument / FEXT with two instruments);
- S/N and Distortion (in the base band);
- Signal Frequency.
By the key is allowed the export on the USB Pen-Drive or PC the image on the
display (in BMP format).
SPECTURM & NETWORK ANALYZER:
This is a powerful analyzer to measure signals and/or noise levels with various input
configurations such as: low and high impedances or DC decoupling to perform special
“sniffer” measurements on powered lines.
In 4 Wire mode, using the tracking generator output (TX) separate from the receiver input
(RTX) it is possible to perform these spectral measurements:
- Insertion Loss of loop lines or channels or various quad-pole devices;
- Crosstalk (NEXT) between two lines or channels.
In 2 Wire mode, using the active bridge and the tracking generator (RTX connector), it
allows:
- Return Loss measurement;
- Longitudinal Balance Loss measurement (limited to Base and Medium Band).
By pushing the key it is possible to freeze the measurement.
Moving the marker by the  arrows, it is possible to read the amplitude and frequency of
any point of the trace on the first two windows at the top right of the display.
In Medium Band by pushing the F1 “F_Max” key it is possible to display the frequency
value of the maximum signal level shown on the display (set by Fc and kHz/Div).
The frequency resolution is 1/100 of the kHz/Div setting (i.e. 10 Hz for 1 kHz/Div.)
Pushing the key it is possible to mark up to four different frequency points associated
to different colors.
By the “Save” key function it is allowed the saving of the measurement on internal memory,
included the four possible markers points.
By the key is allowed the export on the USB Pen-Drive the image on the display (in
BMP format).
