2.5.5 Advanced Filter Settings
Several other digital filter parameters are available for modification. Please refer to Chapter
4 for a thorough discussion of digital filtering with the DXP.
In ProSpect, the filter parameters are accessed via the
Acquisition
tab of the
Settings
panel. Press the
[Edit Filter Parameters]
button and modify settings in the associated
dialog. Modifications for the selected PARSET can be tested by pressing the
[OK]
button,
and saved to nonvolatile memory via the
[Save]
button.
The RS-232 command to modify filter parameters is 0x8B, and the command to save the
current PARSET table is 0x8D. Please refer to the RS-232 Command Specification for
details.
2.5.6 Reading the Current PARSET
The RS-232 command to read the current PARSET table is 0x8C. Please refer to the RS-
232 Command Specification for details.
2.5.7 Saving the Current PARSET to Non-Volatile Memory
In ProSpect, all changes to the current PARSET can be saved to nonvolatile memory via
the
[Save]
button.
The RS-232 command to save the current PARSET table is 0x8D. Please refer to the RS-
232 Command Specification for details.
2.6 Repetitive Configuration of Identical Systems
In cases where many microDXP cards are to be configured identically (or nearly identical)
it may be desirable to ‘carbon-copy’ user settings that have been optimized. This procedure
is supported in ProSpect. Note that gain variations between modules make fine gain tuning
necessary for each microDXP.
2.6.1

In ProSpect select
Download…
from the
Firmware
menu to write the parameters in the
XUP file you created to a second microDXP. Browse to the desired XUP file and location
and press

2.7 Data Acquisition
This section describes the most common data acquisition procedures. The most common
commands (i.e. start/stop run, readout data) are described below. Please refer to the RS-
232 Command Specification (a separate document) for a detailed presentation of all RS-
232 commands. DXP-related documents are available online at:
