The 11A32 and 11A34 amplifier plug-in units are virtually
identical to one another except for the number of channels.
The 11A32 is a dual-trace unit, and the 11A34 is a
four-trace unit. The bandwidth of the 11A32 is slightly
higher than that of the 11A34 in each of the four 11000
Two built-in four-pole bandwidth limit filters (100 MHz and
20 MHz) may be activated to reduce unwanted high frequency
noise at 24 dB/octave for each channel.
Both coarse and fine deflection factors steps are fully
calibrated. At 1 mV/div, the high resolution calibrated dc
offset has a setability of 25 μν and a range of ± 1 V
(equivalent to 16 bits), giving an effective screen height
of 2000 div and permitting absolute dc measurement
accuracies to ±0.4%.
