10.5 Directivity
10-12
Perform the normalize (SHORT) of TEST PORT 2.
(a) [MEAS] {S22 REFL REV}.
(For OPT 11, OPT 13 or OPT 14, [MEAS] {S22 (PORT 2)})
(b) Connect the short standard to TEST PORT 2.
(c) [CAL] {NORMALIZE (SHORT)}.
(d) Remove the short standard.
Connect the load standard to TEST PORT 2 and read the value of directivity from trace
data with the marker.
<Check> : The directivity of TEST PORT 2 (in 23°C ± 5°C)
300kHz to 40MHz : -28dB or less
40MHz to 2.6GHz : -30dB or less
2.6GHz to 3.8GHz : -26dB or less
3.8GHz to 8.0GHz : -22dB or less (R3767CG only))
OPT 12 or OPT 13
300kHz to 40MHz : -28dB or less
40MHz to 2.0GHz : -27dB or less
2.0GHz to 3.8GHz : -22dB or less
• The following Steps thru are only used for OPT 11, OPT 13 or OPT 14.
Perform the normalize (SHORT) of TEST PORT 3.
(a) [MEAS] → {TEST - PORT CONNECTION} → {S33 (PORT3)}.
(b) Connect the short standard to TEST PORT 3.
(c) [CAL] {NORMALIZE (SHORT)}.
(d) Remove the short standard.
Connect the load standard to TEST PORT 3 and read the value of directivity from trace
data with the marker.
<Check> : The directivity of TEST PORT 3 (in 23°C ± 5°C)
300kHz to 40MHz : -28dB or less
40MHz to 2.6GHz : -30dB or less
2.6GHz to 3.8GHz : -26dB or less
3.8GHz to 8.0GHz : -22dB or less (R3767CG only)
OPT 12 or OPT 13
300kHz to 40MHz : -28dB or less
40MHz to 2.0GHz : -27dB or less
2.0GHz to 3.8GHz : -22dB or less
• The following procedure applies to OPT14.
Perform the normalize (SHORT) of TEST PORT 4.
(a) [MEAS] → {TEST - PORT CONNECTION} → {S44 (PORT4)}.
(b) Connect the short standard to TEST PORT 4.
(c) [CAL] {NORMALIZE (SHORT)}.
(d) Remove the short standard.
Connect the load standard to TEST PORT 4 and read the value of directivity from trace
data with the marker.
