PA5 Programmable Attenuator
Overview
The PA5 Programmable Attenuator is a precision device for controlling signal levels over a
wide dynamic range, providing 0 to 120 dB of attenuation for signals up to 100 kHz in
frequency. The device is fully programmable; however, simple manual operation is also
available using front panel controls.
When used programmatically, the module may be controlled via TDT's ActiveX Controls in any
programming environment that supports ActiveX controls, such as Matlab, Python, or
LabVIEW. For information about how to control the module programmatically, see the
When used in manual operation, the attenuation level is adjusted in two modes of operation:
In
Atten
mode, the attenuation level of the signal can be adjusted from 0 to 120 dB in
increments of 0.1 dB.
UserAtt
mode applies user-programmed parameters to adjust the attenuation level.
Before using the UserAtt mode, attenuation parameters must be set up using the UserOps
menu.
