This generator produces both white and pink noise.  It may be used for noise masking (in an office, home, bedroom, waiting room, etc) or for general audio frequency testing.  Picture 4 is my spectrum analyzer showing the low frequency rolloff at about 5 Hz.  Picture 5 shows the high frequency is down about 3db at around 18 kHz.  The rolloff is not very sharp and usable signal extends out beyond 25 kHz. It will provide either a 500 mv line level output or a 5 mv microphone level through either a single ended RCA phono plug or a balanced output with a three conductor socket. The mating plug with screw terminals is included.  There is a low pass filter (high frequency rolloff) that can be adjusted from flat (no effect) down to 9 db / octave at 300 Hz.  It is really great for testing the frequency response of filters, equalizers, speakers and similar audio gear. I will include a copy of the data sheet for both the rack mount and stand alone versions (the unit for sale is rack mount).  The data sheet includes specifications and frequency response graphs.
This generator works fine and is in very good condition.
