If all data values in a specific list are going to be the same value e g the current limit parameter is set to the same value for the entire transient program only the first data value for that parameter has to be set Setting only the first data point will automatically repeat that value for all subsequent points in the transient list Setting Slew Rates Very often output changes must be done as fast as the power source can make them This means the transient list slew rate is set to its maximum value If this is the case for all the data points in the list it is sufficient to set just the first data point s slew rate for either voltage and or current Setting only the first point of any parameter in the list will automatically cause all points for that parameter to be set to the same value This saves a lot of data entry time If however one or more data points require a specific slew rate such as needed to do a ramp all other points have to be specifically set to their required slew rates including the maximum slew rate Saving Transient Lists Once completed a transient sequence can be saved along with the steady state setup of the instrument by using the REGISTER SAVE menu Registers that may be used for this purpose are 1 through 15 It is advisable to do so especially for longer transient lists California Instruments 68 User Manual Rev J 42 8 REGISTERS Menu The registers menu provides access to the non voltage setu
