Performance Test
Checking the directivity
Test equipment:
- Spectrum Analyzer (refer to section "Measurement Equipment and
Accessories", item 1)
-
50 Ohm termination (refer to section "Measurement Equipment and
Accessories", item 4)
- Short Circuit termination (refer to section "Measurement Equipment and
Accessories", item 3)
Test setup:
¾
Mount the R&S FSH-Z2 on to the spectrum analyzer (item 1).
Spectrum Analyzer settings:
-
[ PRESET]
-
[ FREQ ]
- [ START FREQ : 10 MHz ]
- [ STOP FREQ : 3 GHz ]
- [
BW
: MANUAL VIDEO BW : 3 kHz ]
-
[ MEAS
: TRACKING GEN : MEASURE ]
- [ REFLECT CAL : CONTINUE ]
Measurement:
¾
Connect the Short Circuit termination (item 3) to the "TEST" Port of the
R&S FSH-Z2
¾
Press softkey [ CONTINUE ] on the Spectrum Analyzer.
¾
Replace the Short Circuit termination (item 3) on the "TEST" Port of
the R&S FSH-Z2 with the 50 Ohm termination (item 4).
¾
The curve shows the directivity (limited by returnloss of the used 50
Ohm termination, item 4).
Hint:
¾
As far as the datasheet states only typical values, the test limits are
some dB worse than these numbers!
