: 25 mVrms, DC to 100 MHz
55 mVrms, 100 MHz to 120 MHz
: x l, xlO, and xlOO
: 25 mVrms to 500 mVrms (at xl)
: DC to 100 kHz: 100 Vrms (xl), 150 Vrms (xlO or
xl GO)
100 kHz to 120 MHz: 5 Vrms (xl), 50 Vrms (xlO or
xlOO)
: DC or AC coupled, or AUTO (AC coupled)
: Approx. 1 M£2//30 pF, COM. A approx. 500 k£2
: 10 ns
: Approximately —1 V to +1 V continuously variable.
In the AUTO mode, the trigger level is automatically
set to the half-amplitude of the peak value of the
signal to be measured.
: +/— switchable
: COM. handles inputs A and B as common input.
SEP. handles inputs A and B separately.
: Approx. 0.1 ms to 0.1 s. The masking time can be
monitored at CHECK mode.
: 100 kHz low-pass filter
