(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 10 0 kHz (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.
