6.2.1
Timing
The GEMINI RF Power Meter has no triggers or reading clock and cannot deliver precisely
timed readings.
GET
, when applied to instrument readings, does not trigger a new reading.
Instead, the instrument immediately transmits the last-available values. The GEMINI RF Power
Meter always free-runs and produces approximately three readings per second on the display.
Effectively,
GET
transmits the displayed value.
6.2.2
Note for Users of LabVIEW™ Software
The GEMINI RF Power Meter requires a terminating character at the end of any command
string. When using LabVIEW software to develop a custom program, the write buffer constant
must be modified to include a
\n
at the end of the command string.
Figure 3
illustrates this
requirement.

POWER command string.
