FUNC(A/B/C)setstheduration(from0to600seconds)thatthevoltagegeneratorremainsON

atthespecifiedoutputvoltagelevelbeforemovingtoanothervoltagelevel.



6.2.1SetFUNC(A/B/C):

1. EntertheΔV/Δtsettingfirst(RefertotheSetModesection4.3.)

2. TurntheVoltagecontrolknobtoselectthedesiredfunctionandthenturntheCurrent

controlknobtosetthetimeperiod(0to600seconds)forthechosenvoltagelevel.

3.

PressingtheCurrentcontrolknobtogglescoarseandfinetuningofthetimeperiod.

4. Togeneratewaveforms,theFuncA/B/CbuttonisusedinconjunctionwithΔV/Δtbutton(the

timeperiodfromonevoltageleveltoanothervoltagelevel)

5. Usingtheabovefunctionssimultaneously,3reversiblepairs(AB&BA,BC&CB,AC&CA)can

beusedtogeneratewaveforms.



Example1:Pulsewaveformwith3secat10Vand1secat5V.

SetA(Preset1)=5V,setB(Preset2)=10V

SetFuncA=1secondbyturningtheCurrentcontrol

knob

FuncB=3secondsusingthesameprocedureasabove

SetΔta‐b=0,SetΔtb‐a=0



6.2.2GeneratingWaveForm

TogeneratethewaveformpushSHIFTandthenpresstheΔV/Δtbutton

ThewaveformwillrepeatcyclicallyuntiltheSHIFTbuttonandthentheΔV/Δtbuttonispressed.



Example2:Trianglewaveform

SetA=5V,B=10V

SetΔta‐b=3seconds,SetΔtb‐a=3seconds

SetFunc.A=3seconds,SetFunc.B=3seconds



Note:Thewaveformgeneratorcanbeoperatedviatheremoteprogrammingsoftware(with
