4.5 HARDWARE CONTROLS TOOLBAR
4.5.1 INPUT CONTROL
channel A input peak meter
Constantly monitors channel A input signal level vs.full digital input scale.
Controls channel A input polarity.
channel A input sensitivity display & control buttons
Displays the actual input sensitivity (in dBV) of the instrument, i.e. the voltage
level beyond which the hardware saturates. It is possible to modify it in 10dB
steps by pressing the (F9) and/or (F10) buttons.
channel B input peak meter
Constantly monitors channel B input signal level vs.full digital input scale.
Controls channel B input polarity.
channel B input sensitivity display & control buttons
Displays the actual input sensitivity (in dBV) of the instrument, i.e. the voltage
level beyond which the hardware saturates. It is possible to modify it in 10dB
steps by pressing the (SHIFT+F9) and/or (SHIFT+F10) buttons.
Links input channels full scale level controls. If this button is pressed the two
channel sensitivities are set equal and channel A controls act also on channel B.
Selects the Autorange mode. When in autorange mode the input sensitivity is
automatically adjusted by the instrument to achieve the optimum signal to noise
ratio.
4.5.2 INPUT/OUTPUT LOOPBACK
The CLIO Box features an internal loopback which is very useful for performing self
tests.
Connects channel A output to channel A input with an internal relay.
Connects channel B output to channel B input with an internal relay.
4.5.3 GENERATOR CONTROL
CLIO's generator can be controlled from the dedicated toolbar buttons and dialogs;
for a reference about the possible kind of signal you may generate please see
chapter 7.
output level display & control buttons
Displays the actual output level (usually in dBu) of the internal generator. This
level is valid for both output channels. It is possible to modify it in 1dB steps
pressing the (F7) and or (F8) buttons. If the Shift key is pressed
simultaneously then the steps are of 0.1dB increments.
