In "LOGIC" mode, the "LOGIC HIGH" and "LOGIC LOW" keys, when
selected (LED on), are used to change the high (HIGH) and low (LOW)
levels of the logic signal of +10 V to -10 V by steps of 100 mV.
• Adjustment is performed by the encoder.
G
These keys are active only when the "LOGIC" mode has been
selected.
On this BNC, a TTL-level logic signal is available.
• The period of these pulses is that of the signal generated at the output
"MAIN OUT", in phase and with the same duty cycle (values indicated
on the LCD).
• Adjustment of the frequency using the "FREQ" key.
• Adjustment of the duty cycle using the "DUTY" key.
G
The "AMP LEVEL" and "OFFSET" keys have no effect on the
TTL signal.
