• Arm the sweep recording process by moving the cursor to the
REC field and press the enter key. Make sure that the signal
generator is at its lowest sweep frequency when the recording
process is starting.
• The unit detects the start tone (315 Hz or 1 kHz) of an external
sweep and as soon the frequency changes the recording is
automatically started. This status is indicated by the flashing
REC field.
Alternatively, the sweep recording may be started manually
by pressing the enter key with the cursor on the ARM field.
Consequently, ML1 records every incoming signal with a higher
frequency than the previous sample.
• The sweep recording will be stopped as soon as an input signal
with a lower frequency occurs, or as soon as the enter key is
pressed with the cursor on the flashing REC field.
• In order to analyze the sampled curve more detailed, activate the
arrow mode by placing the cursor to the corresponding symbol,
press the enter key, and move the arrow to the sample(s) of
interest by using the left / right keys.
• To zoom in/out the Y-axis, move the cursor to the zoom mode
field, press enter and use the left / right keys.
• To scroll through the Y-axis, move the cursor to the zoom mode
field, press enter and use the up / down keys.
The last recorded sweep curve will be stored internally, even after
leaving the sweep mode or switching off the Minilyzer. As soon as
the frequency sweep mode is re-entered, the curve will re-appear on
the graph, until a new frequency sweep is started.
NOTES • As soon as the sweep mode is entered, the filter
that has been active during the recording of the last
curve will be re-activated.
• The auto power off is disabled during a frequency
sweep recording.
