Drivers | Spectrum

This article explains closed-loop setups using a Spectrum Digitizer and a Spectrum AWG. It shows latency measurement results using the plain PC and also using a CUDA-based GPU for calulcation. This results can be used as a base for own latency-depending setups.

All modern operating systems use a very complex memory management strategy that strictly separates between physical memory, kernel memory and user memory. The memory management is based on memory pages (normally 4 kByte = 4096 Bytes).

Data from the Spectrum digitizers is always delivered by the DMA engine in a multiplexed form. For a 4 channel card that would mean there's a data stream of A0, B0, C0, D0, A1, B1, C1, D1, A2, ...

This article describes the driver installation for old (obsolete) ISA and PCI cards from Spectrum for Windows operating systems. The article covers all legacy PCI.xxx cards and all ISA cards PADxxxx and DAPxxx

The Spectrum hardware driver is not working and shows error 52 ("Windows cannot verify the digital signature for the drivers required for this device"). Either your system is set-up new or you encounter this error message after doing a Windows update.

Drivers for Windows 2000 based systems

The Spectrum M2p/M2i/M3i/M4i/M4x cards and digitizerNETBOX/generatorNETBOX products are delivered with Linux drivers suitable for Linux installations based on kernel 2.4, 2.6, 3.x or 4.x, single processor (non-SMP) and SMP systems, 32 bit and 64 bit systems.

If trying to install the Spectrum kernel driver on a Linux system you get the message:

insmod: ERROR: could not insert module ./spcm.ko: Invalid module format

This article explains the differences between driver types MICX and SPCM and what hardware series is covered by what driver.
