The Model 3500 is ideal for designers, manufacturers, and service and installation providers of RF products. It can be used by both technicians and engineers to take average RF power measurements for design verification, production test, system calibration, troubleshooting, installation and maintenance.

All devices have internal EEPROM, pull-up resistors, an internal 8 MHz precision oscillator and 12 general I/O pins for application use. Alternatively, the I/O pins work as ADC inputs or PWM (Pulse Width Modulation) outputs.

On-Chip Peripherals

Commonly used microcontroller peripherals are all integrated. The ATtiny261/461/861 devices include a Universal Serial Interface (USI), which can be easily configured to work as an SPI, UART or TWI. Advanced analog capabilities, such as built-in temperature measurement, a fast analog comparator and a programmable analog gain amplifier, allow highly-integrated designs with a small price tag. A total of eleven 10-bit A/D converter input channels allow a wide selection of peripherals to be connected in sensor and control applications, and the internal temperature sensor allows reliable system parameter calibration.

The ATtiny261/461/861 excels in battery-powered equipment due to inherently low power consumption and individually-selectable low-power sleep modes. A balance between system performance and power consumption is achieved by directly controlling the system clock frequency. Additional power saving is achieved by selectively turning off timers, the serial interface, and/or ADCs when not in use. As a result, the power consumption of the device in 1.8V active mode at 1 MHz is less than 400 uA and in power-down mode just a few microamps.

Complete evaluation and debug tools are available for the tinyAVR microcontrollers. The STK500 and STK505 starter kits are available at $79 each and offer all the necessary hardware to evaluate programs and test the capabilities of the ATtiny261, ATtiny461 and ATtiny861.

Samples of ATtiny261, ATtiny461 and ATtiny861 are available in 20-pin SOIC and PDIP and 32-pad QFN packages. All three devices are in volume production. Volume prices for 10k units are $0.80, $0.90 and $1.15, respectively.

Despite oil shocks, natural disasters and war, the world economy is chugging along. GDP growth, even with regional variations, is broadly based. This is good news for electronics production and for outsourcing manufacturing.

Test System Development

In terms of test system development, the 6000L Series scopes come standard with IVI-COM (Interchangeable Virtual Instruments) drivers, and they support SCPI (Standard Commands For Programmable Instruments) commands. You can send SCPI commands over any LAN to control the scope.

Beyond that, Agilent's I/O Library Suite lets you readily configure and integrate these instruments into your unique system, even if it includes instruments from other vendors.

The company's press statement also briefly refers to Agilent Open hardware, I/O and software tools. The 6000L Series scopes include the hooks to standard programming environments and languages such as VisualBASIC, C, C++ , and others.
