Introduction
This manual discusses the MA25101A IQ Streaming PCIe kit hardware and software installation and use of
the MX280006A IQ Acquisition Tool. The IQ Streaming PCIe kit has two main components:
•
Windows compatible PCIe interface card that connects to Anritsu analyzers directly through a PCIe
interface port.
•
MX280006A IQ Acquisition Tool (PC software) that interfaces to Anritsu analyzers via Ethernet or
through a PCIe interface.
This chapter covers general information, including references to related documents and system requirements.
covers hardware and software installation.
covers the software overview and basic use of
the controls.
Before You Begin
Ensure that you are familiar with your analyzer by reviewing the
“Additional Documentation” on page 1-4
.
Also, there are several important points that need to be well understood to get full benefit from the
MX280006A IQ Acquisition Tool (PC software). The two main interface types are discussed below.
Using Ethernet
Connection speed matters. The supported analyzers have Gigabit Ethernet ports. This will provide gapless
streaming up to about 40 MHz at 8-bits, 20 MHz at 16-bits, or 10 MHz at 32-bits capture bandwidth. However,
if any element in the Ethernet chain runs at a lower speed, such as at 100 Megabits, then performance will be
seriously degraded. IQ Acquisition Tool cannot detect this, but it will be evident in data throughput. For best
performance, a direct connection is recommended, using a single Gigabit Ethernet hub or switch.
Using PCIe
PCIe is a system bus. The PC expects that devices on this bus are inside the PC case. It was not designed to
connect remote devices so care must be taken when making connections. First, when you power on the PC, it
interrogates the system bus for attached devices. The operating system expects that all devices on the system
bus will power on when power is applied to the bus.
It is important that the analyzer already be connected and running in the supported mode. If you turn on the
analyzer after the PC, it will not be found on the PCIe bus. Also, you would not consider opening the PC case
and removing the bus card while the PC is running. Turning off the analyzer is similar from the PC’s point of
view. Do not expect to power cycle the analyzer without also doing the same with the PC.
Note
Loading the FPGA Image for PCIe Streaming
When the MS2090A boots up, it does not automatically load the FPGA image that supports
PCIe data transfer. The analyzer detects when it is connected to an active PCIe card and will
prompt to load the image. If you choose to load the image, the analyzer will reboot, which takes
about 40 seconds. As discussed above, the PC must be started after the analyzer fully reboots
and begins sweeping. This means that the PC must also be powered up or rebooted after the
analyzer is set up properly, but not before the analyzer has finished booting.
