Level/Frequency Meter Operation
:
1.
Apply left and/or right audio into the SP395’s inputs.
2.
Select the Level Meter Test function.
3.
Select the desired display units.
The same units are selected for both inputs.
4.
Select the measuring range.
It is advised to select auto-ranging or “A” in the top center
toolbar so the SP395 can select the best range automatically. You may hear some artifacts
of connecting a strong signal to an input of the meter when it has auto-ranged to
maximum gain. Connecting a strong signal may cause the display to momentarily say
“OVER” or “UNDER” and you may hear the signal bleed through to the internal speaker.
Note: When the signal is improperly ranged or weak, the display reads “LOW” or “LOW Hz.”
Signal Generator
The SP395 contains a general-purpose, full-featured, crystal-controlled signal generator that
creates test tones and standard noise waveforms. Most of the features of the signal generator are
accessed from any function, using bottom toolbar. These include On/Off, level (in 0.5dB steps),
waveform selection (including USB), and frequency.
The Signal Generator function selection within the TechBench menu provides a bar graph
indication of output level. It further provides a measured level of the actual output to the balance
and unbalanced outputs. It lets you trim the output level + or – 1 dBu.
Note: You can store default values for generator waveform type, frequency, and level, by using
the Save Defaults function in the Setup & Calibration function.
