The numbers listed are those available at
the input connectors. Connecting an atte-
nuating probe will change the value pro-
portional to the probe's attenuation factor.
Query-only Link Response Meaning
? PRObe <qstring> Returns a description of the probe con-
nected to the channel. For a Level 1
TEKPROBE, the query returns "Level 1."
For a Level 2 TEKPROBE, the query re-
turns "Level2/ <probe_type>/ <serial
_nhumber> ." When no TEKPROBE is con-
nected, the query returns "NONE."
? UNIis <qstring> Returns the units of conversion of a probe
connected to the specified channel input.
