Spe ci fi cations Accuracy: +3% Sweep Magnification: 10X, +6% Hold off TRI GGERI NG Variable Modes Maximum External Trigger Voltage 200V (DC + AC peak) Sensitivity Internal - 0.5 division, External - 500 mV Vertical Resolution Horizontal Resolution 1 in 2048, approximately 200 samples/div. Sampling Rate 40 M samples/sec to 4 samples/sec, reduced in proportion to time base. Direct sampling at time base settings of 20 µs/div and slower, equivalent time sampling at time base settings of 10 µs/div and faster Time Base Expander For storage of slow time events, time base steps 10 ms/div and slower have selectable 1/1 or 1/100 rate. 1/100 rate expands time base from 1 sec/div to 50 sec/div in 1-2-5 sequence Equivalent time Sampling Bandwidth Dot Joining 0.1 µs/div to 2 s/div in 1-2-5 sequence, 23 steps. Vernier control provides fully adjustable sweep time between steps 2522C 2048 x 8 bits/channel; (2 k/channel with direct sampling, 1 k/channel with equivalent time sampling) 1 in 256, approximately 25 steps/div.
