NOTE
This action changes menu format from dBm to mW.
(17) Connect RF detector A to CALIBRATOR 1 GHZ output.
(18) Press keys as listed in (a) through (d) below:
(a) MENU key.
(b) F3 key.
(c) F1 key.
(d) Any UNITS key (nS or S or mS key).
(19) Disconnect RF detector A from CALIBRATOR 1 GHZ output.
NOTE
Press CLEAR key to bypass B detector calibration.
(20) Connect RF detector A to POINT A (fig. 2).
(21) Adjust signal generator amplitude controls for a power meter indication equal to
P1 value recorded in (6) above.
(22) Record TI EL display indication as S1.
(23) Adjust signal generator amplitude controls for a power meter indication equal to
P2 value recorded in (12) above.
(24) Record TI EL display indication as S2.
(25) Divide S2 value recorded in (24) above into S1 value recorded in (22) above.
Record results as Y.
(26) Calculate linearity error (percent) using the below listed formula and record the
results in table 3 under the linearity error (%) column. Linearity error will be less than
linearity specification listed in table 3.
Linearity Error (%) = {[(Y/X) -1] x 100}
WHERE:
X = value recorded in (14) above
Y = value recorded in (25) above
