 sorry my late reply, I'm pretty
 busy these days. The behavior you report

| 498 | Sun Apr  3 22:10:19 2016 | Chris Thompson | Trigger on the And of a positive and negative signal | No there are no other components. I put a photo of the inverter with its cables SMA
 and one end, BNC at the other. You can see

| 497 | Sat Apr  2 17:22:34 2016 | Abaz Kryemadhi | Trigger on the And of a positive and negative signal | Thanks again,   this is very useful,  just another question did you
 put any other passive elements in the circuit

| 496 | Sat Apr  2 11:41:07 2016 | Stefan Ritt | Question about timimng calibration | The evaluation board normally has 1024 bins per channel. We offer an option with
 2048 bins using channel cascading, to capture

| 495 | Sat Apr  2 11:21:10 2016 | Felix Bachmair | Question about timimng calibration | Hi, 
 I am trying to understand some
 details about the timing calibration.

| 494 | Fri Apr  1 22:09:07 2016 | Chris Thompson | Trigger on the And of a positive and negative signal | The coilcraft part number is: JA4220-ALB. Iordered two of them and they were sent as
 free samples. You might want to buy some

| 493 | Fri Apr  1 01:30:40 2016 | Abaz Kryemadhi | Trigger on the And of a positive and negative signal | Hi Chris, 
 I am looking at Sensl SiPMs
 as well,  can you send the part number
 |  | 
| 492 | Thu Mar 31 20:48:00 2016 | Chris Thompson | Trigger on the And of a positive and negative signal | I needed a fast pulse inverter in order to feed signals from the recent SensL SiPMs
 into a conventional CFD which only accepted
 |  | 
| 491 | Thu Mar 31 20:38:05 2016 | Abaz Kryemadhi | Trigger on the And of a positive and negative signal | Thanks, that looks just fine.

| 489 | Thu Mar 31 19:44:38 2016 | Abaz Kryemadhi | Trigger on the And of a positive and negative signal | Ok, thanks!  do you know an easy in-line inverter like mini-circuit or digikey?
 Can also redesign the detector I gues to
 |  | 
| 488 | Thu Mar 31 19:35:06 2016 | Stefan Ritt | Trigger on the And of a positive and negative signal | No. You have to use an inverter for one of your signals.

| 487 | Thu Mar 31 19:30:26 2016 | Abaz Kryemadhi | Trigger on the And of a positive and negative signal | I would like to be able to trigger in this fashon:  channel 0 > 0.1 and. channel
 1< -0.1,  because I have a positive
 |  | 
| 486 | Tue Mar 22 12:54:41 2016 | Stefan Ritt |  | Yes this is correct. But it is a sample-and-hold circuit. So the sampling cell follows the
 input for 3.2 ns, then samples and holds

| 485 | Mon Mar 21 10:38:27 2016 | Daniel Dribin | DRS Oscilloscope freezing after a long run | Dear Stefan Ritt, 
 I am using a DRS4 v5 to do timing
 measurements of Positron lifetime. I use

| 484 | Fri Mar 11 19:50:18 2016 | Dominik Neise |  | Hello Stefan, 
 I just stumbled again over a phrase
 in the DRS4 datasheet I never really understood,

| 483 | Wed Mar  9 09:57:20 2016 | Christian D | LabView | Hi, 
 I would like to use the DRS4 board
 with LabView for fast readout.

| 482 | Mon Feb 29 14:09:21 2016 | Stefan Ritt | two DRS4 boards configuration with 2048 samples each | The multi-board mode has never been tested with 2048 samples, so is very likely not to work.
 I don't know yet how much work this will

| 481 | Mon Feb 29 13:33:06 2016 | Dmitry Hits | two DRS4 boards configuration with 2048 samples each | Dear Stefan, 
 I daisy-chained two boards (master
 sn#: 2514 - slave sn#: 2513) each with 2048
