+# In order to interface Perseus hardware, we resolve to use the

+# Below the base options used are shown:
+#
+# -p output    I/Q samples as 32 bits floating point
+# -d -1        suppress debug messages
+# -a           don't test attenuators on startup
+# -t 0         runs indefinitely
+# -o -         output samples on stdout
+#
+# As we are already returning I/Q samples as pairs of 32 bits
+# floating points (option -p),no need for further conversions,
+# so the method getFormatConversion(self) is not implemented at all.
