TRIANGLE WAVE SELECT button.
Pressing this button will enable outputting of a triangle style waveform on main
output,
OUTPUT
jack, and it will be indicated by a lighted
TRIANGLE WAVE SELECT LED.
TRIANGLE WAVE SELECT LED.
LED associated with
TRIANGLE WAVE SELECT
button, it lights when unit
outputs a triangle wave style signal on
OUTPUT
jack.
OTHER PARAMETERS field.
This field is used for showing other parameters’ values of the output signal on the
OUTPUT
jack such as level, offset, duty cycle, sweep time, sweep width or the CMOS output level on
TTL/CMOS
jack. As long as the value of
a parameter during a 7-second period is not changed, the unit will automatically show the output level on the
OUTPUT
jack.
OTHER PARAMETERS identifiers.
This field is associated with
OTHER PARAMETERS
field and will show a message
relevant to the nature of the parameter value shown in
OTHER PARAMETERS
field. As long as the value of a parameter during a 7-
second period is not changed, the unit will automatically display the message identifying the output level parameter.
POWER switch.
Turns power on and off.
FREQUENCY knob
. This knob controls the changing of the frequency within the current frequency range. The value is
displayed in frequency field. The changes are applied upon the start frequency in
EXTERNAL VCG
and
INTERNAL SWEEP
mode.
(See chapter
x
for a detailed explanation).
This knob has no meaning in
FREQCOUNTER
mode.
SWEEP TIME knob.
This knob controls the changing of the time value set for sweeping the range between start frequency
and stop frequency. This knob has no meaning except
INTERNAL SWEEP
mode.
SWEEP WIDTH knob.
This knob controls the changing of the ratio used for calculation of the width of frequency range,
swept in
INTERNAL SWEEP
mode. This knob has no meaning except in
INTERNAL SWEEP
mode.
SWEEP INT/EXT button.
Pressing this button will change the working mode between
EXTERNAL VCG
and
I
NTERNAL SWEEP
. The new mode will be indicated by the lighting of the corresponding LED, INT LED or EXT LED.
EXT LED.
LED is associated to
SWEEP INT/EXT
button and lights when
EXTERNAL VCG
mode is active.
INT LED.
LED is associated to
SWEEP INT/EXT
button and lights when
INTERNAL SWEEP
mode is active.
SWEEP LIN/LOG button.
Pressing this button will change the way the frequency range in
INTERNAL SWEEP
mode will
sweep between linear mode and logarithm mode. The lighting of the corresponding LED, LIN LED or LOG LED will indicate the
working sweep mode. Button is valid only in
INTERNAL SWEEP
mode.
LOG LED.
LED is associated to
SWEEP LIN/LOG
button and lights when logarithm sweep mode is engaged.
LIN LED.
LED is associated to
SWEEP LIN/LOG
button and lights when linear sweep mode is engaged.
DUTY CYCLE knob.
This knob controls the changing of the duty cycle of the output waveform on
OUTPUT
jack. It has
meaning only for
EXTERNAL VCG
and
INTERNAL SWEEP
.
