Fixed vertical gain, coded as an integer.
22 = 5 mV/div
23 = i0 mV/div
24 = 20 mV/div
25 = 50 mV/div
....... 31 = 5 V/div
Values below 22 and above 31 may occur on processed data
records. See Section 7.10.1 for an example of how data
values are converted to volts in processed data records.
Variable vertical gain, in units of 0.005 of unity.
0 = gain of 0.4, 120 = gain of 1.000.
See Section 7.10.1 for an example of how data values are
converted to volts in processed data records.

Vertical offset in units of 0.04 of the vertical
deflection factor, i.e. 0.04 V/div.
0 = - 8 div 25 = - 7 div
50 = - 6 div .....
200 = 0 div 225 = i div
250 =
2 div .....
400 = 8 div
See Section 7.10.1 for an example of how data values are
converted to volts in processed data records.
Input channel coupling at acquisition.
0 = DC, 50 ~
1 = Ground
2 = DC, 1M~
3 = Ground
4 = AC, 1M~
Attenuation of external probe (must have been set up
manually or by remote control)
0 = *I I = *i0
2 = *I00 3 = *i000
This value is already absorbed into the fixed vertical
gain (position 0), it serves only as a reminder here.
Bandwidth limit at acquisition.
0 = off i = on
Time base at acquisition, coded as an integer.
4 = 2 nsec/div 5 = 5 nsecldiv
6 = I0 nsec/div 7 = 20 nsec/div
..... 34 = 20 sec/div
35 = 50 sec/div 36 = I00 sec/div
