The required settings are made in the Auxiliaries panel; the settings described here are
intended as examples.
An in-depth description of the detailed options can be found in Chapter 5, "Instrument
Functions" , on page 195.
"Audio Monitor" switches the monitoring function on or off.
In the "Signal Source" Track / Split row, the "Signal Source" and output voltage at the
monitor outputs ("Volume") can be selected for both monitor outputs together ("Track")
or separately from each other ("Split").
The "Signal Source" field is used to select which signal is to be monitored. This can be
the measurement signal switched to the analysis path either in the "Input" or "Function"
level, i.e. with or without corresponding filtering. The individual levels of the analyzer
are explained in greater detail in the section "Function blocks and measurement lev-
els". Starting with serial numbers 120100, 140100, 180100, two DC voltages independ-
ent of each other in the range from -5
V to +5 V can be output.
The fields "Monitor 1" and "Monitor 2" are used to select which BNC socket is assigned
to which measurement channel.
In the "Volume" field, the level at the BNC sockets is set by entering or changing the
numeric value in the range from -120
dB to 120 dB.
The "Voltage" line sets the DC level at the BNC jacks.
Alternatively, CTRL+F9 of the external keyboard can be used to set the level at the
BNC sockets. A window with a symbolized volume control opens which can be oper-
ated directly with the cursor keys or the mouse.
4.12.2 Trigger output
A trigger output for the following application is on the rear panel:
●
Gen Sync: Output for a signal dependent on the start of the generator that can be
used to trigger external instruments / circuits.
●
Cascade: Reserved for later applications.
4.13 Rapid Deactivation of Outputs
CTRL+F12 of the external keyboard can be used in case of malfunctions to switch off
the outputs of the generator.
The switched-off lines can be reactivated only by pressing CTRL+F12 again.
The switch-off of generator outputs is indicated by the GEN OVLD LED:
●
LED is yellow: The generator outputs were switched off due to malfunctions or
with CTRL+F12 of the external keyboard.
●
LED is red: The generator outputs were overloaded by an external signal feed
>=
of approx. 12 V peak and switched off at high impedance .
