Save/Recall

Management Store and recall setups, waveforms, data base and screen images to both the hard drive and the floppy drive of the PC. Storage capacity is limited only by disk space.

Operating System Microsoft Windows® 95/98/ME/NT4/2000/XP.
Waveform Save/Recall Up to four waveforms may be stored into Waveform Memories (M1-M4), and then recalled on display.
Save/Recall to Disk You can save or recall your acquired waveforms or data base to or from hard disk or floppy disk of PC. To save a waveform, use the traditional Windows "Save as"dialog box. From this dialog box you can create subdirectories, new waveform files, or overwrite existing waveform files. You can load file with a waveform or data base you have previously saved, into one of Waveform Memories, and then recall it on display.
Save/Recall Setups The instrument may store into the memory and then recall complete setups.
Autoscale Pressing the Autoscale key automatically adjusts the vertical of channels, the horizontal scale factors, and the trigger level for a display appropriate to the signals applied to the inputs. The Autoscale feature requires a repetitive signal with a frequency greater than 1 kHz, duty cycle greater than 1%, amplitudes greater than 50 mV p-p (vertical) and 200 mV p-p (trigger). Autoscale is operative only for relatively stable input signals.
