Case Study: BELIeVE with BLE

We have release to discuss a case study from a customer. Early in 2023, an issue arose around Bluetooth LE.  Specifically, there was a question of the bandwidth available to cell phones. Reports had been received of differing behaviours with different handsets. We set out to investigate. What we found surprised us. We were able … Continue reading “Case Study: BELIeVE with BLE”

BELIeVE v 1.4.0 released

Today we have updated BELIeVE with some much-requested features. Our popular 34465A DLL has been enhanced with support for its extended triggering modes and reading multiple data in a single stream. Network testing here shows we can transfer 2,000,000 readings in around 90 seconds. The test engine can process them in the blink of an … Continue reading “BELIeVE v 1.4.0 released”

Popular Use Cases

Here are some examples of what BELIeVE-DV and BELIeVE-QA can do.

Control the Power Supply

Many industry sectors, such as automotive and aerospace, require product operation be verified over an input power range. For example, how does the DUT cope with brownouts (a temporary reduction in the supply voltage) and…

Event Advancement

Many products are designed to enter a certain mode or perform a function after a set number of operations, as part of a maintenance strategy that is based on use rather than time in service,…

Exercise Wired Interfaces

If your product includes wired communication ports, BELIeVE can exercise these – and the comms protocols include USB, Ethernet, CANbus, ARINC-429, MIL-STD-1553, RS-232, 422 and 485, GPIB, I2C, SPI, PCI, SMbus and LVDS. The verification…

Exercise Wireless Interfaces

As with wired interfaces, it is equally important to verify that wireless communications - such as those made over Bluetooth, WiFi, Zigbee, ANT Radio Service, LoRa and other popular protocols - function correctly and are…

Integration / Hardware-in-the-Loop Testing

The verification of control systems is essential in many industries – most notably aerospace, automotive and the nuclear, chemical and petrochemical industries – and hardware-in-the-loop (HIL) testing is a common practice. The control system is…

Measure Power Consumption

BELIeVE can interface with multiple instruments at the same time and all recordings are timestamped and can therefore be correlated. By placing an Ammeter (or DMM in current mode) in-line with the DUT’s power supply…

Program the DUT

By interfacing with industry standards such as JTAG, or vendor specific systems (such as Microchip’s ICSP), in-system programming (ISP) is possible through BELIeVE. Device firmware updates through USB or Bluetooth are also possible. Moreover, any…

Simulate Sensors

BELIeVE can be used to drive a variety of instruments that are designed to simulate the outputs of sensors. For example, some instrumentation OEMs have products that can simulate a thermistor (the resistance of which…

Simulate User Interaction & Hardware Faults

If your product is to interface with mechanical devices such as switches and buttons, BELIeVE can be used to control an interface board. For example, the switching sides of relays on the interface board can…

Software Event/Fault Injection

As software engineers will know there is a technique known as mocking. Used during product development, mocking modifies the system’s code to force certain behaviour; typically to make the DUT interpret inputs in a different…

Test Analogue I/O

Analogue inputs can be exercised in much the same way as the DUT’s input power; i.e. using your benchtop PSU to apply lower and higher values than expected and to make step changes. For more…

Read more
Test Digital I/O

BELIeVE can exercise your product’s digital inputs by driving a digital pattern generator. For example, you may have designed your product to interface with a digital encoder (which outputs Gray code for example) in order…
