Characteristics
CMRR (ADD Mode with
Channel 2 inverted)
Performance Requirements
At least 20:1 at 50 MHz for common-mode signals of eight
divisions or less, with VAR VOLTS/DIV control adjusted for best
CMRR at 50 kHz, at any VOLTS/DIV setting.

100 mV and 500 mV per division.
Within ±10%.
Bandwidth is measured with a leveled, low distortion, 50-fi source,
sine-wave generator, terminated in 50 fi. The reference signal
amplitude is set at the lesser of 6 divisions or the maximum leveled
amplitude. External termination bandwidth is checked with a 4
division reference signal.
Bandwidth with probe is checked using a BNC-to-probe-tip (013-
0227-00) adapter.
Bandwidth with external termination is checked using a BNC 50-fi
feed through terminator (011-0049-01).
Using standard accessory probe.

Performance requirement not checked in manual.
b
lf the instrument is subjected to "greater than" 85% relative humidity, bandwidth is reduced by 50 MHz. After the instrument is
subjected to "greater than" 85% relative humidity, it requires more than 50 hours of operation at "less than" 60% relative
humidity before full bandwidth is restored.
