49. Our calibrated Test Source generates
test signals at user defined frequencies and
power levels. The test signal is of extreme
accuracy, making it the ideal way of testing
the R&S EFL210. And indeed, this picture
does not lie: using the HDMI-output of the
R&S EFL210 connected to my test computer
(which has a HDMI capture card), I put both
windows side by side. Look at the result:
I generated a -40 dBm signal at 130 MHz
and on the other side of the cable, the R&S
EFL210 measured -40.7 dBm at exactly
130.00 MHz. An excellent result.
50. I repeated the same test at 180 MHz. Now
I got only -0.1 dBm deviation.
51. At 950 MHz I got -0.2 dBm difference.
52. Again, only -0.5 dBm difference at 1450
MHz
53. Finally, at 2150 MHz, the deviation was
+0.1 dBm.
54. Wondering, why I got a higher deviation
at the first measurement, I decided to repeat
