Output Button

The output button enables/disables the pulse output.

Menu Button

This button is for navigating the PDG-2520 menus.

Enter Button

Used for variables that will be permanently stored in the unit or require
setup times internal to the PDG-2520. When a question mark appears
after the variable, the enter button will “confirm” or in some cases save
that particular setting.

Up Arrow Button

The UP ARROW button allows the user to go up in any particular menu to
change selections. If the user is at the top selection it will wrap back
around to the bottom selection.

Down Arrow Button

The DOWN ARROW button allows the user to go down in any particular
menu to change selections. If the user is at the bottom selection it will
wrap back around to the top selection.

X10 Button

The X10 button is used when varying parameters that have exponents
that can change by a power of 10. By pressing the X10 button the user
can increment the exponent within its acceptable range. This allows the
user to quickly set the parameters, without having to excessively scroll the
encoder wheel. The X10 button functions with the following commands:

Set Pulse Width 1, 2, 3, and 4

Set Delay 1, 2, 3, and 4

Set Frequency (*Note: if depressed while dialing in frequency it will
increase the frequency at a much higher rate)

Set Counters/Bursts/Packets

The X10 button is effectively a 10X multiplier. For example, when
setting frequency, the resolution of the encoder wheel is three digits
(i.e. 1.00Hz, 10.0Hz, 100Hz, 1.00KHz). Therefore without adjusting
the range, the encoder wheel must be turned many times to
increase the frequency from 1Hz to 100Hz. However if the
frequency is set to 1.00Hz, if the X10 button is pressed once, it
changes to 10.0Hz. If it is pressed twice, it changes to 100Hz.

Setting the delay and pulse width is similar to setting frequency. For
example, to set the delay to 300ns, set the delay to 25ns, press the
