The value for the lower frequency AGC capacitors is given by the following schematic and formula.
To predict AGC settling requirements, use the following formula:
Where: F is frequency in Hertz
Use of the external AGC capacitors can also have an effect on distortion. The SWR200 data sheet shows an in-
creasing distortion with decreasing frequency starting at 1500Hz. This effect is entirely due to time constants within
the AGC circuitry which are correctable with the inclusion of C3 and C4.
Among the application possibilities provided by frequency range enhancement of the SWR200, mention should be
made of the use of the SWR200 as an ultra-precise 60Hz source. This can have wide application in 60Hz testing
and generation.
