L = 6Ω (noninductive load), Rg = 600Ω, VG = 40dB

Notes.

All tests are measured using a constant-voltage supply unless otherwise speciﬁed.

Available time for load short-circuit and output noise voltage are measured using the transformer supply speciﬁed below.

The output noise voltage is the peak value of an average-reading meter with an rms value scale (VTVM). A regulated AC supply (50Hz) should be used to eliminate the

effects of AC primary line ﬂicker noise.
