| Digital Mode Specifications |
| Storage Word Size |
2048 x 8 bits/channel; (2 k/channel with direct sampling,
1 k/channel with equivalent time sampling). |
| Vertical Resolution |
1 in 256, approximately 25 steps/div. |
| 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. |
