j. Check that the instrument meets the bandwidth specification at --3 dB
(--6 dBm in readout) as listed in Table 4--16. Enter value on test record.
13. Disconnect the hookup: Disconnect the cables and adapters from the
instruments.
Sine Wave Generator Leveling Procedure
Some procedures in this manual require a sine wave generator to produce the
necessary test signals. If you do not have a leveled sine wave generator, the
following procedure to level the output amplitude of your sine
wave generator.
Equipment
required
Sine wave generator (I tem 12)
Level meter and power sensor (Item 13)
Two male N to female BNC adapters (Item 15)
One SMA-to-BNC adapter (Item 19)
Two precision coaxial cables (Item 4)
Prerequisites See page 4--17
1. Install the test hookup: Connect the equipment as shown in Figure 4--47
(start with the sine wave generator connected to the instrument).
2. Set the Generator:
H Set the sine wave generator to a reference frequency of 10 MHz.
H Adjust the sine wave generator amplitude to the required number of
divisions as measured by the instrument.
