General Information

The DN2.44x series allows recording of up to 8 channels and the DN6.44x series even up to 24 channels in the high speed high resolution segment. Due to the proven design a wide variety of 14 and 16 bit digitizerNETBOX products can be offered. These products are available in several versions and different speed grades making it possible for the user to find a individual solution.
The digitizerNETBOX products can be used with maximum sample rates of up to 130 MS/s, 250 MS/s or 500 MS/s using either two, four or eight (SE) channels with the DN2.44xx models and with 12, 16, 20 and 24 (SE) channels using the DN6.44x models. The installed mem­ory up to 4 GSample per DN2 digitizer unit or up to 12 GSample per DN6 digitizer unit will be used for fast data recording and can com­pletely be used by the current active channels. If using slower sample rates the memory can be switched to a FIFO buffer and data will be transferred online over Ethernet to the PC memory or to hard disk.
Application examples: Laboratory equipment, Super-sonics, LDA/PDA, Radar, Spectroscopy.

digitizerNETBOX Overview

The series of digitizerNETBOX products are remote powerful digitizer instru­ments with GBit Ethernet connection following the LXI Core 2011 standard. The proven internal digitizer modules, a stable chassis, an embedded remote con­troller, sufficient air cooling and standard BNC connectors form an unique in­strument that opens a lot of new application areas.
The digitizerNETBOX can be either directly connected to a PC or Laptop or it can be connected to a company/institute LAN and can be accessed from any PC within that LAN. Using the digitizerNETBOX offers the following benefits and new possibilities compared to digitizer plug-in cards:
• Use a powerful digitizer without opening the PC and without mounting hard­ware inside the PC.
• Share the digitizer within a group of engineers that only need the instrument from time to time.
• Place the digitizer directly near the signal sources and control it remotely from the desk.
• Use the instrument at different location without moving a complete system. One just needs the digitizerNETBOX, a few cables and a Lap­top.
• Use the digitizer as s mobile data acquisition device with the DC power option (DN2.xxx only).

Internal Digitizer Modules Introduction

Internal Digitizer Modules

The digitizerNETBOX products internally consist of either digitizer modules that are accessed and programmed in a similiar way as the Spec­trum digitizer cards themselves.
Accessing the digitizerNETBOX by software therefore is nearly identical to accessing the same plug-in cards. Throughout the manual all programming and software usage will be described for the internal digitizer mod­ules.

Dynamic parameters are measured at ±1 V input range (if no other range is stated) and 50Ω termination with the samplerate specified in the table. Measured parameters are averaged 20 times to get typical values. Test signal is a pure sine wave generated by a signal generator and a matching bandpass filter. Amplitude is >99% of FSR. SNR and RMS noise parameters may differ depending on the quality of the used PC. SNR = Signal to Noise Ratio, THD = Total Harmonic Distortion, SFDR = Spurious Free Dynamic Range, SINAD = Signal Noise and Dis­tortion, ENOB = Effective Number of Bits.

Warnings

ESD Precautions

The digitizerNETBOX/generatorNETBOX products internally contain electronic components that can be damaged by electrostatic discharge (ESD). The grounded chassis itself gives a very good protection against ESD.
Before connecting signals to the digitizerNETBOX/generatorNETBOX it is recommended to bleed off any elec­trostatic electricity.

Opening the Chassis

There are no components inside the chassis that need any operating by the user. In contrary there are a lot of components that may be harmed when operated unproperly by a use.
As Spectrum only gives a warranty on the complete instrument, opening the chassis will make you loose the warranty.

Cooling Precautions

The high performance digitizers/generators of the digitizerNETBOX/generatorNETBOX operate with components having very high power consumption. Therefore the digitizerNETBOX/generatorNETBOX models have sufficient cooling fans.
Make sure that the air inlets and air outlets are free and uncovered and in case of a DN6 ensure that the installed filters at the inlet are cleaned regularly.
DN2 airflow:
DN6 airflow:

Sources of noise

The digitizerNETBOX/generatorNETBOX is using electrical components with very high resolution and high sensitivity. The signal inputs will acquire your signals with a high quality but will also collect spurious noise signals from various sources - especially if using the inputs in high impedance mode. To minimize this effect the cabeling must be made with care.
Keep away the cables from any sources that may inject noise into the signals like other instruments, crossing or even worse running in parallel with other cables with high frequency signals on them. If possible use dif­ferential signalling to minimize the effectes of injected noise.

Installing 19“ rack mount option for DN2

This option is an extra that has to be ordered separately. It can be ordered with the digitizerNETBOX/generatorNETBOX from the beginning or it can be ordered later on, if it is becomming necessary to mount the digitizerNETBOX/generatorNETBOX into a 19“ rack. In any case the digitizerNETBOX/generatorNETBOX comes pre-configured as a standalone unit, which has to menually be converted to the rackmount configuration by the user.
Step 1
The rackmount option comes with the required Torx T20 size screw driv­er to un-mount the default screws holding the bumper feet.
Unscrew these 8 Torx T20 screws with the provided screw driver and keep them together with the un-mounted bumpers for possible later use in case the rackmount option shall be un-mounted again in the future.
Step 2
Mount the 19“ rack mount extension using the four phillips-head screws that are also provided with each rack mount extension. Two screws are required for each rack mounting bracket.
Care should be taken to not overtighten the screws.

Installing 19“ rack mount option for DN6

Installing the rack mount extension for the DN6 series follows the same principles as for the DN2 models shown above.
Step 1
Unscrew the existing bumper corner pieces with the provided screw driver and keep them together with the un-mounted bumpers for possi­ble later use in case the rackmount option shall be un-mounted again in the future.
Step 2
Mount the 19“ rack mount extension using the four phillips-head screws that are also provided with each rack mount extension. Two screws are required for each rack mounting bracket. Care should be taken to not overtighten the screws.
In addition to using the provided rack mount extension for fastening the DN6 device within the 19“ rack, the user must take additional measures, suitable for the used rack, to provide adequate mechanical support at the backside of the device.
This support is required for DN6 devices due to their higher weight compared to DN2 devices.

Detecting the digitizerNETBOX Hardware Installation

Detecting the digitizerNETBOX

Before accessing the digitizerNETBOX/generatorNETBOX one has to determine the IP address of the digitizerNETBOX/generatorNETBOX. Normally that can be done using one of the two methods described below:

Discovery Function

The digitizerNETBOX/generatorNETBOX responds to the VISA described Discovery function. The next chapter will show how to install and use the Spectrum control center to execute the discovery function and to find the Spectrum hardware. As the discovery function is a standard feature of all LXI devices there are other software packages that can find the digitizerNETBOX/generatorNETBOX using the discovery func­tion:
• Spectrum control center (limited to Spectrum remote products)
• free LXI System Discovery Tool from the LXI consortium (www.lxistandard.org)
• Measurement and Automation Explorer from National Instrumen
• ts (NI MAX)
• Keysight Connection Expert from Keysight Technologies
Additionally the discovery procedure can also be started from ones own specific application:
#define TIMEOUT_DISCOVERY 5000 // timeout value in ms
const uint32 dwMaxNumRemoteCards = 50;
char* pszVisa[dwMaxNumRemoteCards] = { NULL }; char* pszIdn[dwMaxNumRemoteCards] = { NULL };
const uint32 dwMaxIdnStringLen = 256; const uint32 dwMaxVisaStringLen = 50;
// allocate memory for string list for (uint32 i = 0; i < dwMaxNumRemoteCards; i++) { pszVisa[i] = new char [dwMaxVisaStringLen]; pszIdn[i] = new char [dwMaxIdnStringLen]; memset (pszVisa[i], 0, dwMaxVisaStringLen); memset (pszIdn[i], 0, dwMaxIdnStringLen); }
// first make discovery - check if there are any LXI compatible remote devices dwError = spcm_dwDiscovery ((char**)pszVisa, dwMaxNumRemoteCards, dwMaxVisaStringLen, TIMEOUT_DISCOVERY);
// second: check from which manufacturer the devices are spcm_dwSendIDNRequest ((char**)pszIdn, dwMaxNumRemoteCards, dwMaxIdnStringLen);
// Use the VISA strings of these devices with Spectrum as manufacturer // for accessing remote devices without previous knowledge of their IP address

Finding the digitizerNETBOX/generatorNETBOX in the network

As the digitizerNETBOX/generatorNETBOX is a standard network device it has its own IP address and host name and can be found in the computer network. The standard host name consist of the model type and the serial number of the digitizerNETBOX/generatorNETBOX. The serial number is also found on the type plate on the back of the digitizerNETBOX/generatorNETBOX chassis.
