Measure for at least 10 sweeps, record the average value of
sdev(1)
in Table 7
for LT37x or LT354 and Table 7A for LT26x.
!
Repeat the above 3 steps for Channel 2, Channel 3 & Channel 4 substituting
channel controls and input connector. Record the measurements in Table 7 for
LT37x or LT354 and Table 7A for LT26x.
!
Repeat the above measurement for all channels for 1.1 MHz, 10.1 MHz,
100.1 MHz, 250.1 MHz and 500.1 MHz and record the values in Table 7 for
LT37X or LT354. For LT26X, use Table 7A for frequencies of 1.1 MHz, 10.1
MHz, 100.1 MHz, 175.1 MHz & 350.1 MHz. For LT584, use Table 7B for
frequencies of 1.1 MHz, 10.1 MHz, 100.1 MHz, 250.1 MHz, 500.1 MHz & 1000.1
MHz.
!
Calculate the ratio to .3MHz for each frequency.
Ratio = (sdev of XXXMHz) / (sdev of 0.3MHz)
and compare the results to the limits in the test record.
