What is wrong with the amplitude value of 5.19 Vpp is that it is a bit wrong (too big), due to

the noise on the Probe Comp signal. You can see that the dashed horizontal cursor lines

are positioned above and below where they should be (on the top and bottom of the

waveform).

Get rid of the noise by pressing Acquire hardkey, and then the Averaging softkey (and average

8 waveforms). We can see that with averaging on, the amplitude is now 4.979 Vpp, 4 % lower

than 5.19Vpp. The dashed cursor lines now lie right on the top and bottom of the waveform.

Features to Try – Saving Waveforms to a Floppy Disk:

The Default Setup does NOT change the how waveforms are saved to a floppy disk. You

should be sure to check that your oscilloscope file format for saving waveforms is TIF. This can

be selected by using the Utility hardkey, then the Print Confg softkey followed by the Format

softkey where TIF is selected.

Another graphic file Format choice is BMP (bitmap). While this is also easily imported into

Word, it takes twice as long to write the file (e.g. PRINT_01.BMP) to the diskette, and the file is

much bigger (about 6 times bigger!). The last choice for file format is CSV; this is Comma-

Separated Value format. It is not a graphic file, but is suitable for importing into a spreadsheet

program.

1) Get a waveform on the display, perhaps by connecting Channel 1 probe to the Probe Comp

output terminal, and press the Autoscale hardkey.

2) Use the Quick Meas hardkey to measure frequency, peak-peak voltage, and period. The

first two happen automatically; you must press the Period softkey to measure period.

3) With a floppy disk in the 3.5-inch disk drive under the display, press the Quick Print

hardkey. The displayed waveform, including the frequency, peak-peak voltage, and period,

will be written to a file on the floppy disk. If it’s the first waveform saved, the file will be called

PRINT_00.TIF.
