DSK-300-S
Sub-band Frequency Agile –Television Modulator
1.) INTRODUCTION
The Olson Technology DSK-300-S consists of one sub-band frequency agile F.C.C. compatible modulator
in a 5 ¾”D x 6 ¾”W x 2”H desktop chassis. The DSK-300S may be operated at 45dBmV typical,
+40dBmV guaranteed minimum. No IF loops are provided on this modulator.
The DSK-300-S modulator will operate on any sub-band, standard, or cable channel from 5MHz –
300MHz. All channels are selectable by front panel DIP switches and a front panel adjustment allows setting
to F.C.C. offset frequencies, HRC frequencies are available.
Note: The DSK-300-S is shipped with channel T7 selected.
The DSK-300-S offers the unique Olson Technology feature of >76dB out-of-band C/N ratio. SAW
filtering is used for adjacent channel operation and provides typically 60dB of spurious free dynamic range.
The DSK-300-S has low power consumption for economical and reliable long-term operation.
2.) CHANNEL SELECTION
Channel frequencies are selected by setting the 10-position DIP switch (visible through the vertical slot in the
front panel). The front panel is illustrated in figure 1.

Switch-setting codes for sub-band channels are shown in Table 1. Switch-setting codes for standard
channel frequencies can be found in Table 2 in this manual, HRC code settings are shown on Table 3. The
front panel illustration in Figure 1 shows a switch properly set for sub-band channel T7.
