The VFD will now indicate the 19kHz pilot or subcarrier frequency to be measured as illustrated in the
following sample:
1 9 k H z P i l o t
C a r r i e r t o E x i t
A momentary push of the SELECT switch located between the DN and UP switches will start the
measurement, with the resulting level indicated on Carrier Modulation LED display. The pilot-subcarrier
levels are indicated on the top meter legend. The FM stereo pilot level is typically set to 9% injection.
During the 19 kHz pilot level measurement the VFD will indicate:
1 9 k H z P i l o t
D a t a t o E x i t
As indicated on the second line of the VFD, a momentary push of the DATA – DISPLAY switch at this
point ends the pilot-subcarrier level measurement for the 19kHz pilot. The VFD now displays:
1 9 k H z P i l o t
C a r r i e r t o E x i t
From this point, the UP and DN switches can be used to select another subcarrier frequency to be
measured or the Carrier Modulation Select switch can be used to exit the Sub-Pilot injection level
measurement mode.
If the UP and DN switches are used to select another subcarrier frequency to be measured, in this case
the 57kHz SCA, the process is identical to that described above. In this example, the VFD now
indicates the 57 kHz subcarrier frequency is to be measured:
5 7 k H z S C A
C a r r i e r t o E x i t
A momentary push of the SELECT switch located between the DN and UP switches will start the
measurement, with the resulting level indicated on Carrier Modulation LED display. The 57kHz
subcarrier level is indicated on the top meter legend. During the 57kHz pilot level measurement the
VFD will indicate:
5 7 k H z P i l o t
D a t a t o E x i t
As indicated on the second line of the VFD, a momentary push of the DATA – DISPLAY switch at this
point ends the pilot-subcarrier level measurement for the 57kHz pilot.
