You can use the "Auto-Detect" feature to setup the I/O connection to your power supply.Use the Source - I/O Configuration menu.
If you are using a Serial connection, the power supply address parameters must be set to: Baudrate 9600, 8 bit, Flow NONE, Parity NONE, Handshake NONE.
Press the "Measure" button to acquire a new voltage or current waveform. Waveforms are not automatically updated.
The display on the front panel of the power supply will blink when the Software is making measurements. 
"I don't want to join the kind of a club that accepts people like me as members."  -Groucho Marx
You can Zoom In by dragging a box around an area of the waveform.  
Waveforms can be stored on disk and recalled for later use a reference waveforms.
Reference waveforms should be obtained using a triggered measurement. The trigger level should be placed at the same level for all reference waveforms.
When measuring the DC and RMS values of a waveform, be sure to measure an intergral number of cycles. Use the vertical markers to fine tune the caclulated measurement area.
If you cannot find a Horizontal or Vertical marker, turn the marker OFF, then back ON again and it will be place inside the display area. 
Only the active waveform is used for calculated measurements. A new measurement from the power supply will replace the active waveform.
The HP 66300 series of power supplies offers micro-Amp current measurement capability in low range.
You can move the trigger level with the mouse by clicking on the trigger marker and dragging.
HP 66300 series supplies offer current sinking ability to test battery chargers in UUTs
The HP 66300 series supplies with the high peak current option (#J03) provides more capability in the less space for digital wireless products.
If at first you dont succeed, prehaps skydiving isnt for you.
You can move the vertical markers by holding down the Shift or Ctrl keys and using the left and right arrow keys.
Use the Edit-Copy command to copy the waveform and measurement display to the Windows clipboard.
The waveform files are simple ASCII text files that can be imported into spreadsheet and word processor programs for further analysis.
I have a dog with no nose. -- Oh yeah, how does he smell?  Terrible.
Waveforms that contain negative current pulses can be displayed using the Autoscale function.
Hanning sense measurement windows should only be used when more than 5 cycles of a waveform is being measured. The Software turns uses rectangular windows for all triggered measurements.
The Calculated measurements displayed on the bottom of the screen are based on the section of waveform between the vertical markers if they are on.
Beware any philosophy that will fit in this space.
