6 - 50 THE CPL PROTOCOL
6.8 SETUP
The Query Setup (QS) and Program Setup (PS) commands can be used together
in order to retrieve and restore a complete or partical setup of the oscilloscope.
When a setup is requested from the oscilloscope, it will send its setup as a
sequence of strings. Each separate string describes a setup node. By adding a
parameter to the QS command a particular setup node can be queried.
So the query program could be:
PRINT #1,"QS" Complete setup
PRINT #1,"QS",2 Only node 2 (channel 2 settings)
PRINT #1,"QS",S Only node S, where S must be one of the
values specified below.
Node numbers (S) can have the following values:
hex dec meaning
01 1 Channel 1 settings
02 2 Channel 2 settings
03 3 Not used
04 4 Ext trig settings
(nodes above: attenuator, display on/off, coupling DC/AC, GND,
Invert, 50
/1 M
, continuous(var)/discrete, position control)
0E 14 Probe Scale settings
(scale value, scale unit)
0F 15 Common vertical settings
(add 1+2, alt/chop, bandwidth limiter on/off, number of traces,
average, envelope).
10 16 Common horizontal settings
(X-deflection on/off, mode auto/trig/single/multiple, X-deflection
source, magnify, acquisition length, X-position.
11 17 Main Timebase settings
(timebase speed, triggering edge/TV, MTBI on/off, MAIN TB on/off,
trigger slope pos/neg, TV trigger F1/F2/line, noise suppression
on/off, continuous(var)/discrete, level-pp on/off, trigger source,
trigger coupling, TV trigger normal/hdtv)
12 18 Delayed Timebase settings
(timebase speed, trigger mode edge/tv, DEL’D TB on/off, edge
trigger slope pos/neg, edge trigger source, trigger coupling)
