User Manual – Rev AJ California Instruments4.2.6.3 FREQUENCY SWEEP/STEP sub menuFigure 4-14: FREQUENCY SWEEP/STEP SETUP ScreenThe Voltage sweep and step screen shown in Figure 4-14 can be reached from the transientr when trying to leave thisurn to the TRANSIEThe FREQ SWEEP/STEP screeDURATION l take tow rate ofdiately.nscreen as follows:1. Scroll to the FREQ SWEEP/STEP entry using the up and down cursor keys.2. Press the ENTER key to bring up the FREQ SWEEP/STEP screen.The FREQ SWEEP/STEP screen has several data fields. All data fields that are blank to theright of the equal sign must be filled or an error message will occuscreen. The EVENT # is the last data field to be filled. Entering the event data field will cause thedisplay to ret NT screen where a new selection can be made.n has the following fields:Duration is amount of the time the output frequency wilreach the END FREQ level. Duration will define the slethe output frequency for the event. A duration of 0 seconds willcause the output frequency to reach the end frequencyimmeEND FREQ This is the output frequency at the end of the transient event iHz.END DELAY This is the time delay the frequency will stay at END FREQbefore it proceeds with the next transient event or completesthe transient.FUNCTION [3Pi Controller only] This field can be used to select the waveshape to be used during this step of the transient sequence.Each step can use a different wave shape from the availablelibrary of 50 user-defined waveforms or the three standardwaveforms. The output wave shape changes upon entry intoeach step and remains in effect for the duration of the step. Thedefault wave shape is always the SINE (sine wave).REPEAT This is the number of times the FREQUENCY SWEEP/STEPtransient will repeat before it will proceed to the next event orexit the transient. The number of times the transient event isgenerated is equal to the REPEAT + 1. Leave this value at zeroif only one execution of this event in the list is required.EVENT # This must be the last item in the transient edit screen. All datafields must be entered before inserting the EVENT #. TheEVENT # takes value from 1 to 99. The EVENT # defines theorder of execution of the transient events in a multiple eventtransient. It is a good practice to enter spaced EVENT #’s toallow insertion of an EVENT later if needed. (For example,space them by 5.) Entry of a sequence EVENT # number willcause the display to return to the TRANSIENT screen.MX Series 97
