FRONTPANELCONTROLSAND CONNECTORS
B TRIGGER
B Input Connector : When selected,providesa means forconnecting the triggersignal.
B ARM Jack:Gates the B Input.A logicalHi gatesthe B Input off and a logicalLo gatesthe A Input on.
SLOPE Switch : Selectswhether the positive-or negative-goingslope of the signalisto be used as a trigger.
The inward positionof the SLOPE switch selectsthe positiveslope and the outward positionof the SLOPE
10
switchselectsthe negativeslope.
COUPL Switch :Selectsthe input coupling to be used. The outward positionof the COUPL switch connects
both the DC and AC component of the B Input to the attenuator.The inward positionallowsonly frequencies
above approximately 5 Hz to pass.
P-P SENS
.1V, 1 V, 10 V Positions: Selectthe sensitivityof channel B triggeramplifier.

TRIG SOURCEPosition:Selectsthe internalverticalamplifiertriggersignalwhen installedin a horizontal
compartment .
LEVEL Control:Controls the DC levelof the channel B triggeramplifier. The PRESET Position(LEVEL
13control fullyclockwise)setsthe DC triggerlevelto 0 volts.
TRIG LEVEL Jack: May be used to monitor the DC triggerlevelor,when the P-P SENS switch isinthe TRIG
SOURCEposition,the TRIG LEVEL jackcan be used to externallysetthe DC triggerlevel.
