PXIe-5185/5186 Calibration Procedure
50
Ω
and 1 M
Ω
Devices
Early versions of the PXIe-5185/5186 support only 50
Ω
input impedance. Check the part
number of your device to see what input impedance is supported by your device:
•

L (where
x
is any letter and

input
impedance. These devices require NI-SCOPE 3.8.7 or later.

L (where

Ω

Ω
input
impedance. These devices require NI-SCOPE 3.9.6 or later.
50
Ω
devices need to be tested for only 50
Ω
input impedance because they have no 1 M
Ω
input.
Software Requirements
Calibrating the PXIe-5185/5186 requires installing the NI-SCOPE instrument driver on the
calibration system. Refer to the
50
Ω
and 1 M
Ω
Devices
section to see which driver version your
device requires. You can download the NI-SCOPE instrument driver from the NI website at
ni.com/downloads/drivers
. NI-SCOPE supports programming a self-calibration and an
external calibration in multiple application development environments (ADEs). When you
install NI-SCOPE, you need to install support for only the ADE that you intend to use.
LabVIEW support is in the
niScope.llb
file, and all calibration functions appear in the
NI-SCOPE Calibration palette. For LabWindows
™
/CVI
™
users, the NI-SCOPE function panel,
niScope.fp
, provides access to the available functions.
For the locations of files you may need to calibrate your device, refer to the
NI-SCOPE Readme
,
which is available on the NI-SCOPE media.
