3. Software Setup
Before attempting to setup the Converter, refer to the Callisto
Software Setup Guide
for detailed instructions on
using the Callisto software and the Frequency Genie software tool. Setup the UPC-590L-M Converter according
to the steps below, while referring to the screenshots immediately following:
1. Connect all equipment; double-check all coaxial cable and power connections and power supply
voltages. Refer to the LWA Antenna and LWA Power Coupler instruction manuals for connection and
powering details;
2.
Apply power to LWA Power Coupler, UPC-590L-M Converter, and Callisto instrument;
3. Open callisto.exe and obtain a spectral overview (OVS) of the sky. This records the relative sky noise
power at each frequency within Callisto’s frequency range 45 to 870 MHz with 62.5 kHz resolution. This
range includes frequencies within the up-converter IF output range and also includes frequencies
outside the range. When finished with this step close callisto.exe;
4. Open the Frequency Genie software tool and load the spectral overview from step 3;
5.
For the UPC-590 up-converter, setup Frequency Genie as follows:
Channel selection method: Minimum detection (see Note)
Type of converter:
Upconverter (IF=RF+LO)
Sweeplength:
200
RF Startfrequency (MHz):
5
RF Stopfrequency (MHZ):
85
LO (converter)(MHz):
200
Filenumber FRQxxxxx.cfg:
00000 to 99999 (example, 00585)
Note: To prepare a frequency list based only on equal spacing of the channels, select Equally Spaced;
however, strong radio frequency interference (RFI) may exist on some channels and the frequency
list with equal spacing may require manual editing.
6.
To view the frequency range on the Spectral Overview, click the Preview FrqPrg button on lower-right of
the Frequency Genie main window. The programmed frequency range will be shown as a green slanted
line;
7.
Click the Save Program button on the upper-right of the main window to generate the frequency list;
8. Move or copy the frequency list file to the same folder as callisto.exe;
9. Edit callisto.cfg parameter [frqfile] to use the frequency file from step 7. It may be necessary to reduce
the Callisto gain parameter [agclevel] due to the gain of the LWA FEE. A new setting will have to be
found experimentally. See section 2. Installation – Signal levels for additional information.
