6. Connect Frequency Counter to 83522A RF OUTPUT. Connect a i-1 Vdc power supply
to rear penel FM INPUT. A shift in frequency of approximately -20 MHz should occur
on the Frequency Counter when +1 Vdc is applied. (This shows correct FM
modulation sensitivity.) Reconnect Delay Line Discriminator to RF OUTPUT and
connect function generator to rear panel FM INPUT connector.

A5R.31 (Figure 5-30) so amplitude at 100 Hz and at 100 kHz are the same k0.2 cm on
CRT. Refer to Table 5-2 for the allowable range of values for A5R31.
