EXP RISE AND EXP DECAY ARE A SET OF PULSES.  EXP RISE HAS AN
EXPONENTIAL LEADING EDGE ON THE PULSE AND A RAPID RETURN TO THE BASE
VALUE FAST FALL TIME.  EXPDECAY IS THE COMPLEMENT.  THE PULSE
APPEARS TO SHOOT STRAIGHT UP FAST RISE TIME AND DECAYS
EXPONENTIALLY.  ON AN OSCILLOSCOPE, MULTI TONE LOOKS LIKE THE DUAL
FREQUENCY OUTPUT FROM PRESSING A BUTTON ON AN OLD TELEPHONE KEYPAD.
THE FREQUENCY OF THE LOWER TONE IS ADJUSTABLE USING THE FRONT PANEL
BUTTONS, BUT THE FREQUENCY OF THE SECOND TONE IS NOT.  ON THE LCD,
THE SINC PULSE WAVEFORM LOOKS LIKE A SPECTRUM DISPLAY OF A NARROW
PULSE.  ON THE SCOPE IT IS A TRAIN OF SPECTRUM LIKE PULSES.  A
NUMBER OF EXPLANATIONS OF THE SINC WAVEFORM CAN BE FOUND BY
SEARCHING ONLINE.  IT APPEARS TO BE A WAVEFORM USED IN ADVANCED
FILTER DESIGN.  ANOTHER ADVANCED WAVEFORM, LORENZ PULSE, IS ALSO
AVAILABLE.  FINALLY, THERE ARE 15 MEMORY CHANNELS THAT CAN BE
PROGRAMMED WITH WAVEFORMS OF YOUR CHOOSING.  COUNTER AND
MEASUREMENTS PRESSING THE MEAS BUTTON SWITCHES THE UNIT FROM
GENERATING SIGNALS TO MAKING MEASUREMENTS.  THE EXT.IN BNC CONNECTOR
PROVIDES AN INPUT CONNECTION.  THE SOFT SWITCH LABELS ON THE LCD
LIST VARIOUS MEASUREMENTS YOU CAN MAKE.  FIGURE 9 SHOWS A PORTION OF
THE MEASUREMENT SCREEN IN THE PC SOFTWARE.  THE INPUT FREQUENCY IS
3500003R00 HZ, OR 3R5 MHZ.  THE GATE SIZE MAY BE CHANGED AND THE
COUPLING IS SELECTABLE BETWEEN AC AND DC.  THERE ARE SEVERAL CHOICES
FOR THE MEASUREMENT SELECTION DROPDOWN MENU.  CHANGING THIS
SELECTION FROM FREQUENCY TO CYCLE PRODUCES A READING OF ABOUT 2R857
MICROSECONDS.  OTHER CHOICES FOR MEASUREMENT ARE POSITIVE PULSE
WIDTH, NEGATIVE PULSE WIDTH, AND DUTY CYCLE.  SET YOUR OWN WAVEFORM
SELECTING THE ARBITRARY TAB ALLOWS YOU TO DESIGN YOUR OWN WAVEFORM.
UNFORTUNATELY, THERE ARE NO USEFUL INSTRUCTIONS IN THE INFORMATION
BOOKLET, BUT I DID FIND A HELPFUL ONLINE TUTORIAL AT WWW. FACECLIPS.
NET/ VIDEO/ DDGUN OCNMG/ KOOLERTRON SI. HTML.  FIGURE 10 SHOWS A
MODIFIED SINE WAVE THAT I CREATED BY PLACING MY MOUSE CURSOR ON THE
WAVEFORM AND DRAGGING IT UP AND TO THE RIGHT.  THEN I STORED THE
MODIFIED WAVEFORM IN STORAGE LOCATION 1.  YOU CAN ALSO USE THE MOUSE
TO HAND DRAW ANY WAVEFORM YOU WANT.  FINAL THOUGHTS THE KOOLERTRON
DUAL CHANNEL SIGNAL GENERATOR OFFERS A NUMBER OF USEFUL FEATURES FOR
THE AMATEUR WORKSHOP.  IF YOU DONT NEED TO GENERATE SINE WAVES AT 60
MHZ, 15 AND 30 MHZ MODELS ARE AVAILABLE AT LOWER COST.  ADDITIONAL
