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.
Unused
Vertical offset in units of 0.04 of the vertical
deflection factor, i.e. 0.04 V/div.

See Section 7.10.i for an example of how data values are
converted to volts in processed data records.
Input channel coupling at acquisition.
0 = DC, 50 Q
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
1 = *i0
2 = *100
3 = *1000
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
1 = on
Time base at acquisition, coded as an integer.
4 = 2 nsecldiv
5 =
5 nsec/div
6 = 10 nsecldiv
7 =
20 nsec/div
.....
34 =

35 = 50 sec/div
36 = 100 sec/div
