8 INSTALLING A CUSTOM LOAD

8.1 Disassemble the DSTS-5A by first

removing the hex nut from the

IN/OUT BNC connector on the front

panel. Refer to illustration 1 and

remove the black plastic outer bezel

on the back panel (the side with the

RS-232 connector) by lifting it near

the center on the top and sides where

the catches are located. When the

bezel is off hold the DSTS-5A so the

IN/OUT connector is facing upwards

and slide the back panel out of the

housing. Save the two lock washers located on the IN/OUT BNC connector and be

sure to replace them during re-assembly. Note: Do not remove the front bezel. The

front panel should not be removed, only the back panel.

8.2 Install the new load resistor, R24 and a parallel capacitance , C31 if required. Be sure

to move the jumper, J5, to the position closest to the front panel.

8.3 Re-assemble the DSTS-5A making sure the two lock washers are in place on the

IN/OUT connector. If necessary bend the ground contact slightly so it contacts the

front panel when the unit is assembled.
