Sweep
9.6
Return Time
Return time specifies the number of seconds to return from the stop frequency to the
start frequency.
When [Sweep] is enabled, press the
or knob to change the return time.
The default value is 1s and the settable range is from 1ms to 50Ks.
9.7
Hold Time
The hold time specifies how long time the waveform stays at the stop frequency.
When [Sweep] is enabled, press the
or knob to change the hold time.
The default value is 1s and the settable range is from 1ms to 50Ks.
9.8
Mark Frequency
When the output signal frequency is less than the specified mark frequency, there will
output the low level signal from the [FSK/Trig/Sync/Extmod] connector on the rear
panel. When the output signal frequency is at or greater than the specified mark
frequency, the signal outputs on the [FSK/Trig/Sync/Extmod] connector will change
from low level to high level.
When [Sweep] is enabled, press
or the direction keys and knob to modify the mark frequency. The default value is 500Hz
and the settable range is limited by the "Start Frequency" and "Stop Frequency".
9.9
Sweep Trigger Source
The sweep trigger source could be internal, external or manual. The generator will
generate a sweep output when a trigger signal is received and then wait for the next
trigger signal.
When [Sweep] is enabled, press
manual. The default is internal.
⚫
internal: The generator outputs continuous sweep waveform at a rate determined
by the total of the specified sweep time, return time and hold time.
⚫
external: The signal generator receives the trigger signal from the
[FSK/Trig/Sync/Extmod] connector on the rear panel. A sweep will be generated
once the connector gets a TTL pulse with specified polarity. To set the TTL pulse
polarity, press Polarity to select "Positive" or "Negative". The default is "Positive".
⚫
manual: A sweep will be generated from the corresponding channel once you
press [Trigger] at the front panel.
