Ω
, 20 pF (Typical *)
Maximum input voltage:
• When input impedance is 50
Ω
: 5 V
rms
• When input impedance is 1 M
Ω
:
• 40 V (DC+AC
peak
) when DC
≤
input frequency
≤
100 kHz
• {3.5/f + 5}V (DC + AC
peak
) when 100 kHz
≤
input frequency
≤
100 MHz, “ f ” indicates
frequency in MHz.
Ground: Connected to the case’s ground.
* Typical values are described in terms of typical of average performance. However, they cannot
be guaranteed.
CAUTION
Never apply a voltage exceeding the maximum input voltage to the input terminals.
Damage to the input terminals may result.
Note
When you use a probe with this instrument for the first time, its phase must be corrected before use as
described in 3.6, “Compensating a Probe (Carrying Out Phase Correction)”. If the phase is not corrected,
the gain will not be constant across different frequencies. Phase correction must be carried out for each
channel.
