In enforcement, meticulous Equivalent Calculation unit 202 can be further used for every adjacent two pretreated sampled datas to carry out interative computation.
In enforcement, counter 204 can be further used for the interative computation to every adjacent two pretreated sampled datas, counts from zero; Meticulous trigger controller 205 can be further used in the time that the count value of counter 204 equals iterations, controls meticulous Equivalent Calculation unit 202 and stops interative computation.
In specifically implementing, in Fig. 2, oscillograph, under the control of central control unit 206, triggers pretreatment unit 201 and stop immediately sampled data buffer memory or delay process after triggering occurs, and pretreated is like this exactly to trigger near sampled data of moment.Meticulous Equivalent Calculation unit 202 carries out interative computation to pretreated sampled data and produces iterative data, improves constantly the temporal resolution that triggers the moment.Wherein, iterations is produced according to sampling rate and equivalent precision by meticulous trigger controller 205, and meticulous trigger controller 205 carries out interative computation according to the meticulous Equivalent Calculation of the iterations control unit 202 producing.Concrete, meticulous Equivalent Calculation unit 202, in the time carrying out interative computation, is that every adjacent two pretreated sampled datas are carried out to interative computation.To the interative computation of every adjacent two pretreated sampled datas, counter 204 counts from zero, and often carries out an interative computation and carries out one-accumulate; In the time that the count value of counter 204 equals iterations, meticulous trigger controller 205 is controlled meticulous Equivalent Calculation unit 202 and is stopped interative computation.

1, calculation level A obtains a W1 with the central value of putting B, then a W1 and triggering level is compared, and known trigger position is between a W1 and some B;
2, calculation level W1 obtains a W2 with the central value of putting B, then a W2 and triggering level is compared, and known trigger position is between a W2 and some B;

4, calculation level W2 obtains a W4 with the central value of putting W3, then a W4 and triggering level is compared, and known trigger position is between a W2 and some W4;
W1, W2, W3 and W4 are exactly the iterative data producing by interative computation.After the 4th step completes, the resolution of meticulous equivalence has reached 1/16 of the sampling period.Further, from the principle of dichotomy, use this meticulous Equivalent Calculation unit 202, only need to use n step to calculate and can reach the sampling period 1/2

If iteration n=4 time, equivalent precision is 1/16,4 iterative datas that insert, enter comparer 203 relatively, suppose that iterative data is less than triggering level output high level 1, iterative data is greater than triggering level output low level 0, iterative data equals triggering level output high level 1, and the comparative level obtaining in Fig. 4 is 1100, and meticulous trigger controller 205 can calculate meticulous equivalent position information according to comparative level, calculate by following formula, obtain meticulous equivalent position information: m=2
3× 1+2
2× 1+2
1× 0+2
0× 0=8+4+0+0=12; Central control unit 206 is according to meticulous equivalent position information m to showing that data are offset control, and the concrete skew control equivalent offset time can be by following formula m × T/2
ncalculate.And for example W4 is just in time positioned in triggering level, output low level 0 when iterative data W4 equals triggering level, and the comparative level of final output is 1101, meticulous equivalent position information can be calculated as follows and draw: m=2
3× 1+2
2× 1+2
1× 0+2
0× 1=8+4+0+1=13.And for example iteration 5 times, comparative level is 10101, meticulous equivalent position information can be calculated as follows and draw: m=2
4× 1+2
3× 0+2
2× 1+2
1× 0+2
0× 1=16+0+4+0+1=21.
