Need some help…
I’m using a NI GPIB-USB-HS with Ubuntu 12.04 LTS. I’ve got it working but am experiencing slow reads when I compare it to running under Windows with the NI drivers. When running under Ubuntu each read takes 9 milliseconds but the same code under Windows with the same devices takes < 1 millisecond. Have I set the Linux-gpib (V3.2.17) up incorrectly?
Under Windows the settings are:
System controller
I/O Timeout 13 (10 sec) Xrom usb devices driver download for windows.
Autopolling
Send EOI at End of Write
Don’t terminate read on EOS
EOS Byte 0
Don’t Set EOI with EOS on Write
Assert REN when SC
Bus Timing 2 (500 nsec)
Under Ubuntu the config file is:
interface {
minor = 0 /* board index, minor = 0 uses /dev/gpib0, minor = 1 uses /dev/gpib1, etc. */
board_type = 'ni_usb_b' /* type of interface board being used */
name = 'violet' /* optional name, allows you to get a board descriptor using ibfind() */
pad = 0 /* primary address of interface */
sad = 0 /* secondary address of interface */
timeout = T10s /* timeout for commands */
eos = 0x0 /* EOS Byte, 0xa is newline and 0xd is carriage return */
set-reos = no /* Terminate read if EOS */
set-bin = no /* Compare EOS 8-bit */
set-xeos = no /* Assert EOI whenever EOS byte is sent */
set-eot = yes /* Assert EOI with last byte on writes */
/* settings for boards that lack plug-n-play capability */
base = 0 /* Base io ADDRESS */
irq = 0 /* Interrupt request level */
dma = 0 /* DMA channel (zero disables) */
/* pci_bus and pci_slot can be used to distinguish two pci boards supported by the same driver */
/* pci_bus = 0 */
Spirent Communications Inc
/* pci_slot = 7 */
master = yes /* interface board is system controller */
}
And in the code we set:
// Enable system control
ibconfig(IEEE_boardID, IbcSC, true );
if( (ThreadIbsta() & ERR))
{
report_message ( QString( 'ibconfig error' ));
}
// Enable REN line
Vatech Mobile Phones & Portable Devices Driver download. ibconfig(IEEE_boardID, IbcSRE, true );
if( (ThreadIbsta() & ERR))
{
report_message ( QString( 'ibconfig error' ));
}
// Enable 500ns timing
ibconfig(IEEE_boardID, IbcTIMING, 2 );
if( (ThreadIbsta() & ERR))
{
report_message ( QString( 'ibconfig error' ));
}
device_ = ibdev(board_id_, // Board
addr_, // address end device
NO_SAD, // secondary address
T10s, // timeout
Spirent Communications Plc
1, // EOI enabled
0 // No end character
);
So it looks like we’ve set everything as Windows? Am I expecting too much of the Linux gpib driver?
Thanks you in advance.

09 Feb Spirent Report: 5G Activity Accelerates as Operators Look to Differentiate
Insights from over 600 global 5G engagements in 2020 reveal roll-outs continue to gather pace, despite the challenges of the global pandemic
HOLMDEL, N.J.–(BUSINESS WIRE)–#5G–Spirent Communications plc (LSE:SPT), the leading provider of test, assurance, and analytics solutions for next-generation devices and networks, today released its second annual 5G outlook report, based on analysis and takeaways from over 600 global 5G engagements in 2020. The “5G 2021: Market Drivers, Insights & Consideration” report provides insights from across the 5G eco-system on the current status of 5G, illustrating the accelerated timetables from service providers in upgrading to 5G standalone (SA) with the new 5G Core, and revealing how 5G is driving new initiatives and sector engagements. The report is available at www.spirent.com/assets/the-spirent-2021-5g-report.
“2020 was certainly a year to remember, not just because of the unprecedented challenges presented by COVID-19, but also because of the rapid development for the telecom industry,” said Spirent Head of 5G Strategy, Steve Douglas. “Telecom is keeping its sights firmly focused on 5G’s future, not in spite of the challenges of the pandemic, but because of them, and our latest report gives an unparalleled view of the current status of 5G and the trends we’re seeing for the year ahead, based on the investments, research, testing and innovation by the leading 5G players.”
The report draws on Spirent’s work with operators, network equipment manufacturers, government, military, and device makers across the globe. It provides an updated, behind-the-scenes view of what’s gone right so far, where challenges persist, and how what was learned during the year is impacting priorities for 2021 and beyond. Key findings from the report include:
– 5G SA core timetables accelerated rapidly: 5G activity surged in 2020 with accelerated timetables from service providers to deliver 5G SA core deployments, following non-standalone’s (NSAs) inability to really wow customers and deliver a solid new revenue proposition. Service Provider engagement increased nearly 50% as Service Assurance integration ramped up, and leading operators accelerated 5G standalone network strategies and new 5G core deployments.
– Because 5G is moving so fast, operators are turning to partners to deliver key elements: Through service contracts, elements that would previously have been delivered inhouse are now being delivered by trusted partners, as operators need to be able to move quickly to keep up with the complexity of 5G and the accelerated timetables.

– 5G is driving new initiatives and engagements: The year saw notable growth in engagements with government, military and academia around 5G experimentation and security initiatives, as governments explore new use cases. Other notable initiatives include Cloud hyperscalers exploring operator edge partnerships, Open RAN being explored in support of supply chain diversity initiatives, and multichannel video programming distributors (MVPDs) accelerating their plans for 5G.
– Automated Assurance and 5G are the new dynamic duo: Whether it was a core network buildout, lab certification, or new service delivered, 5G plus Automated Assurance were the dynamic duo that customers turned to as they sought to continue pushing forward with their 5G plans, with 80% of Spirent’s assurance business focused on 5G work.
– The trend of accelerated timetables is here to stay: While the pandemic has undoubtedly accelerated 5G timetables, it seems likely this accelerated trend is here to stay.

“In many ways, the pandemic has accelerated trends that we hadn’t anticipated gaining steam for at least another couple of years,” said Douglas, “whether fixed wireless access driven by working from home, or automation required to safely conduct field testing with limited personnel. While there were delays, by and large 5G powered ahead and remained in control of its destiny.”
“Spirent provides us with a real-world glimpse into 5G deployments today,” said Patrick Kelly, Founder and Principal Analyst at Appledore Research. “Spirent has a unique perspective in the 5G ecosystem as a leader in test and assurance solutions. The report provides insights into the current status of 5G and what’s coming next, particularly in 5G core, transport, network security, Open RAN progress, and the role of automated assurance.”
Spirent’s “5G 2021: Market Drivers, Insights & Consideration” report offers a broad view of market-wide 5G challenges, opportunities and plans, and is available as a download at https://www.spirent.com/assets/the-spirent-2021-5g-report.
