The CAEN Mod. N6740 is a 32 ch 12 bit 62.5 MS/s (65 MS/s using external clock) NIM Waveform Digitizer with 2 Vpp single ended input dynamics on a ERNI SMC connector. 32 channels can be available on LEMO connectors using the A746D adapter. A version with 10 Vpp (single ended) input full scale range is also available (N6740C).
The DC offset adjustment (range ±1 V / 5 V) by a programmable 16 bit DACs (one for each 8-channel group) allows a right sampling of a bipolar (Vin = ±1 V / 5 V) up to a full positive (Vin = 0 ÷ +2 V / 10 V) or negative (Vin = 0 ÷ -2 V / 10 V) analog input swing without losing dynamic resolution.

ERNI SMC 68P connectors

USB connector 787780-2 (B-Type)

USB connector for data readout and flow control for Mod. N6740, N6740C

Consult our connectors reference page for technical information.

The module features a front panel Clock Input and a PLL for clock synthesis from internal/external references. The data stream is continuously written in a circular memory buffer. When the trigger occurs, the FPGA writes further N samples for the post trigger and freezes the buffer that can be read by USB or Optical Link. The acquisition can continue without dead time in a new buffer.

Each channel has a SRAM Multi-Event Buffer of 192 kS divisible into 1 ÷ 1024 buffers of programmable size. The readout (by USB or Optical Link) of a frozen buffer is independent from the write operations in the active circular buffer (ADC data storage).
N6740 supports multi-board synchronization allowing all ADCs to be synchronized to a common clock source and ensuring Trigger time stamps alignment. Once synchronized, all data will be aligned and coherent across multiple N6740 boards.

The trigger signal can be provided externally via the front panel Trigger Input as well as via the software, but it can also be generated internally thanks to threshold self-trigger capability.

N6740 houses USB 2.0 and Optical Link interfaces. USB 2.0 allows data transfers up to 30 MB/s. The Optical Link supports transfer rate of 80 MB/s and offers Daisy chain capability. Therefore, it is possible to connect up to 8/32 MCA modules to a single Optical Link Controller (Mod. A5818/A4818).

Software available (Windows and Linux):
CAEN provides drivers for all the different types of physical communication channels, a set of C and LabView libraries (CAENComm and CAENDigitizer), demo applications and utilities:

  • CAENUpgrader: tool that allows the user to update the firmware of the digitizers, change the PLL settings, load, when requested, the license for the pay firmware and other utilities.

  • CAEN WaveDump: software console application that can be used to configure and readout event data from any model of the CAEN digitizer family and save the data into a memory buffer allocated for this purpose.

    • Bandwidth: 30 MHz
    • Programmable DAC for Offset Adjustment (one for each 8-channel group): ±1 V (±5 V)
    • Absolute max. input voltage: 6 Vpp (for 2 Vpp input range version) with Vrail max. to +6V or -6V for any DAC offset value

    Digital Conversion

    • Resolution: 12 bit
    • Sampling rate: up to 62.5 MS/s simultaneously on each channel (65 MS/s using external clock)

    System Performance

    ENOB: 11.20 (48 kS Buffer)
    SINAD: 69.20 dB
    THD: 87.10 dB

    SFDR: 94.9 dB
    SIGMA: 0.50 LSB rms (48 kS Buffer, open input)

    ADC Sampling Clock generation

    Supports three operating modes:

    • PLL mode: internal reference (62.5 MHz local oscillator)
    • PLL mode: external reference on CLK_IN
    • PLL Bypass mode: external clock on CLK_IN drives directly ADC clocks (Freq.: 10 ÷ 65 MHz)

    Digital I/O

    • CLK_IN (AMP Modu II):
      – AC coupled differential input clock LVDS, ECL, PECL, LVPECL, CML(single ended NIM/TTL available by custom cable)
      – Jitter <100 ppm
    • TRG_IN (LEMO 50 Ω, NIM/TTL): external trigger input
    • GPI/GPO (LEMO 50 Ω, NIM/TTL): programmable front panel input/output

    Acquisition Memory

    • 192k sample/ch (3 ms @ 62.5 MS/s) or 1.5M sample/ch (24 ms @ 62.5 MS/s) Multi-event Buffer divisible into 1 ÷ 1024 buffers
    • Independent read and write access
    • Programmable event size and pre/post-trigger

    Common Trigger

    • External (signal on TRG_IN)
    • Software (by USB or Optical Link)
    • Self trigger (internal threshold self-trigger generated by each 8-channel group)

    Trigger TimeStamp

    31-bit counter, 16 ns resolution, 17 s range(*)
    (*)Trigger Logic and Trigger Time Stamp counter operate at 125 MHz (i.e. 8 ns or 1/2 ADC clock cycles), while the counter value is read at a frequency of 62.5 MHz (i.e. 16 ns).

    ADC and Memory controller FPGA

    One Altera Cyclone EP3C16 per 16 channel

    Multi Modules Synchronization
