Optical Filters Checks (TDS 500D/TDS 700D Only)
The procedure that follows verifies that the frequency response of the combined
P670xB and TDS500D/700D oscilloscope system is a Fourth Order Bessel
Thompson Filter which is within limits.
Nominal Filters are available with Option 2C. Reference Receiver Filters are
available with Options 3C and 4C. Options 3C and 4C are not available without
2C, and 3C and 4C are not available on the TDS 794D.
You can verify Option 2C is enabled on the TDS 794D by pressing MEASURE,
then selecting Masks from the Measure pop-up menu. Table 1–8 lists the
available vertical scale factors for each option. Tables 1–9, 1–10, and 1–11 list
the available filters and their specifications.
