Note 1: "F.LOCK" on the display is used to verify that the frequency
indicated is slaved and therefore, in the guaranteed specifications
Note 2: "GATE" on the display is present at each internal "verification" of the
displayed frequency.
Note 3: The "FREQ" key, related to its display, is deactivated into a single
continuous signal.
The "AMP LEVEL", key when selected (LED on) is used to adjust the
amplitude of the "LEVEL" output signal from 0 to 20 V peak-to-peak in an
open circuit.
• Adjustment by encoder with automatic range change.
• The output signal amplitude is indicated on the secondary display:
G
The "AMP LEVEL", with its display, is deactivated in DC
mode alone.
The "OFFSET", key when selected (LED on) is used to adjust the DC
voltage of the "MAIN OUT" output signal from -10 to +10 V
peak-to-peak in an open circuit.
When the "OFFSET" key is selected during the modes
enables the superimposing of a DC voltage to the output signal generated.
• Adjustment by the encoder.
• The signal level is indicated on the secondary display:
G
A long press on the "OFFSET" key is used to reset the value of
the offset to 0 V
The "OFFSET" key is inactive in "LOGIC" mode.
The sum of DC voltage + AC voltage must never exceed ± 20 V. If
necessary, readjust the offset level or the signal amplitude.
The "DUTY" key, when selected (LED on) is used to adjust the duty cycle
of the "MAIN OUT" signal and "TTL OUT" signal between 20 % and 80 %.
• Adjustment by the encoder by steps of 1%.
• The duty cycle is indicated on the secondary display:
G
A long press on the "DUTY" key is used to reset the value of the
duty cycle to 50 %.
The "DUTY" key is inactive in DC voltage mode only.
