2-O. Delay
Add the following at the end of the “Variable Range” paragraph:
“No warning adjustment range: 0.00 ns to at least 85.9% of the period
(95% can be achieved with periods
us).”
Page 2-9. Double Pulse Delay
Heading “Minimum Period”: delete 133.4 ns and insert:
“134 ns (approx 7.5 MHz; double pulses at 7.5 MHz simulates a 15 MHz signal).”
Heading “Range”: substitute the following:
“Range: 20.0 ns to 999 ms (max value: period
width
Hi-Z source resistance, the
minimum range
to typically 30 ns, and the maximum decreases to typically
period width 10 ns.
warning’ adjustment range:
Range minimum: 104% of Width
Range maximum: at least 85.9% of period -width (for periods
us the maximum is 95% of
period -width).”

Identify the connectors of the high power attenuator; the end connected to the 8
should
be marked “IN” and the other end “OUT”

Identify the connectors of the high power attenuator; the end connected to the DVM should be
marked “IN” and the other end “OUT”

The
feedthrough should be at the DVM-end of the cable.

Pollution Degree 2
Warning: To prevent electrical shock, disconnect the HP model
from mains before cleaning.
Use a dry cloth or one slightly dampened with water to clean the external case parts. Do not
attempt to clean internally.
