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 The max slew rate can be set by entering a value of 0 When the enter key is pressed the value will change to 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 MX15 85 User Manual Rev M California Instruments 4 2 8 REGISTERS Menu The registers menu provides access to the non voltage setup storage of the power source A total of 16 front panel setups can be stored in registers numbered from 0 through 15 Each register except register 0 can hold the complete front panel setup including the programme
