(7) MASK
The signal to be measured is masked by pressing 1 to light the lamp
within the switch. Set the masking time with control d). (FREQ. A can
not be masked.)
® MASK TIME
A control for setting the masking time.
@ SLOPE
Trigger point slope selector switch. + sets the trigger point at the positive
slope and — sets it at the negative slope.
@ LEVEL
A control for triggering the signal to be measured at the proper level.
The trigger voltage can be adjusted within a range of about —1 V to
+1 V.
(H) SENS.
Selects the input sensitivity.
@ FILTER
When the switch is set ON, the 100kHz (approx.) low-pass filter is
activated on both A and B channels.
(13) LEVEL
See @ .
@ AC-AUTO-DC
Input coupling selector switch. AC and AUTO cut out the DC compo
nent and routes the AC component into the input circuit. AUTO auto
matically sets the trigger voltage to the 50% level of the voltage to be
measured. DC routes both AC and DC components into the input
circuit.
(0) INPUT B
Channel B input connector.
@ SEP./COM. A
SEP. is used for two separate inputs A and B, whereas with COM. A the
signal to be measured on channel A is common to both channels.
