6.3.3. Star t / Stop Trigger M odeThe S ta rt /Stop t rigger will work in 3 modes:

1. Interlaced with frame a ccumulation.2. Interlaced with field a ccumulation.3. Non-interlaced with field accumula tion.

The exposure time is controlled by t he interval be twe en the ext. t rigger pulse a nd the ext. VD signa l. Theexposure sta rts a t the first HD pulse a fter the falling edge of the ext. trigger, a nd sto ps a t the rising edgeof t he VD pulse . The ra nge ca n be within 1/77 to 1/10,000 s ec.The St a rt/Sto p mode is a continuous mode whe re the VD signal must b e g iven continuously. It is notpossible to input e xt. VD randomly.For the interla ced mode s 2 ext. trigger pulses should be a pplied for ea ch fra me. It is one for ea ch field.In this wa y it is pos sible to ha ve different exposure time for the 2 fields w ithin a n interlaced fra me.The difference b etw een interla ced fra me a ccumula tion or field a ccumula tion ca n be explained a s follow.Both modes have 2 fields output in an interla ced frame. With fra me a ccumula tion the conte nts in the

ODD and EVEN sync. fields will come from sensing field 1 a nd 2 on the CCD sensor. With fielda ccumula tion bo th ODD a nd EVEN sync. field will conta in the s ignal from sensing field 1 a nd 2 a dde dtogether.Non-interla ced w ith field accumulat ion needs only 1 trigger pulse fo r each field.

Cautions in the Star t / Stop Trigger M ode.

1. The input of ext. VD signal must be g iven continuously to s ynchronize with int. VD signal. It is notposs ible to input ext. VD signa l ra ndomly.

2. The exposure sta rt ma y delay up to 1H max., when the falling edge of ext. trigger pulse is notsynchronized with the fa lling edg e of e xt. HD signa l. To a void this 1H jitter a nd de lay, the fa lling edg eof the ext. trigge r pulse sho uld be synchronized within 4.4 usec. to the HD pulse . It can be t he ext. HDinput o r the interna l HD output.Shown under cautions in Edge Pre-select Mode page 7.

3. In this mode, t he ext. trigger ha s t o be TTL level (2.0 to 5.0 V). It ca nnot be 75 Ohm termina ted . Thedurat ion should be more than 1 H nega tive going. >64 sec. a nd < 1 mse c. The input is AC coupled.

4. If the ext. VD input a nd ext. HD input a re from a source with TTL level, set SW2-1 a nd SW2-2 on

6.3.4. Long Time Exposure M odeThe Long t ime exposure will wo rk in 3 modes:

1. Interla ced with field a ccumulation.2. Interlaced with frame a ccumulation.3. Non-interlaced with field accumula tion.

The exposure time is the interva l betw een 2 e xt. VD pulses s ent t o t he ca mera VD input. Each e xt. VDpulse will reset a nd resta rt the interna l VD in the ca mera a s for ext. HD/VD input. So the ca mera issynchronized to the external HD/VD supply after each VD input.An exposure sta rts a fter input o f an external VD pulse, a nd ends a fter the next input of ext. VD, whicha ga in sta rts a new exposure.The long t ime exposure is a continuous process where ea ch external VD will synchronize the ca mera,sto p an exposure, sta rt a new exposure a nd read out the previous a ccumula ted s ignal as interla ced ornon-interlaced fields.The exposure cont rol can be done by feeding every N th VD pulse from the externa l HD/VD supply t o t he

ca mera. N is the w a nted exposure time in number of fields. This is typically done in the frame g rabberPC.The ra nge for long time exposure is from 1 V (a s ingle field) to . However the d a rk current s ignal willincreas e by longer time, s o >2 seconds a re not recommended a t norma l ambient tempera ture.
