SR850 Basics
output voltages of X, Y or R in trace output calcu-
lations. For example, a trace which is defined as X
and output through CH1 or CH2 increases its
output voltage by the expand factor when X is
expanded. This is because the output voltage of X
is expanded.
The output voltage scales for the individual quanti-
ties are listed below.
X,Y,R (signal/sensitivity-offset)xExpandx10V

1V
F 5V - 10V for each octave in frequency.
For example,
1000 Hz = 5V
1200 Hz = 6V
1600 Hz = 8V
1800 Hz = 9V
1990 Hz = 9.95V
2000 Hz = 5V (next octave)
The octaves are defined as follows,
...
62.5 Hz - 125 Hz
125 Hz - 250 Hz
250 Hz - 500 Hz
500 Hz - 1000 Hz
1 kHz - 2 kHz
4 kHz - 8 kHz
8 kHz - 16 kHz
