New AC Source with Power Line Disturbance Simulator

B&K Precision recently introduced the 9801 AC power source, which is a compact 19″ half-rack, single-phase AC source that outputs up to 300 VA and measures AC power characteristics. You can operate the AC source in a 0-to-300-V continuous sweep range or 150-V/300-V auto-switching range with adjustable start and stop phase angle control. With a built-in power line disturbance (PLD) simulator, list, sweep, and dimmer mode, the 9801 is suitable for simulating various AC power conditions. It provides a complete solution for manufacturing, R&D, and precompliance testing applications.9801_front-B&K

For certain compliance testing applications, manufacturers may need an AC source to simulate various AC power line outlets and disturbances. This includes evaluating a product’s immunity to less than ideal input voltage situations such as dips, surges, and dropouts. Therefore, programmable AC sources with built-in power line disturbance simulation functions can be an invaluable tool for testing devices under these conditions.

The 9801 features a low distortion, single-phase AC output with programmable RMS voltage up to 300 V, maximum RMS current up to 3 A, and adjustable frequency from 45 to 500 Hz. The power source is also capable of delivering up to 12-A peak current.

Provided on the front panel is a universal AC output socket and an easy-to-use rotary knob to set AC waveform parameters. The bright VFD display continuously displays the output voltage, peak and RMS current, frequency, power factor, apparent/true power, and elapsed time. The rear includes an additional AC output terminal block for wire connection and an external BNC connector for output On/Off control and monitoring, external triggering, and synchronization. Users will also benefit from the 9801’s standard RS-232, USBTMC-compliant USB, and LAN interfaces for remote control and programming.

Built-in simulation functions include list mode with PLD simulator, sweep, and phase-cut dimming output. The simulation modes allow users to program varying steps of voltage, frequency, width, slope, and disturbances, sweep the output voltage and frequency, and control the phase cut-off of the AC sine wave’s leading or trailing edge. For pre-compliance testing, voltage fluctuations and frequency simulations can be set up according to IEC61000-4-11, IEC61000-4-14, and IEC61000-4-28.

Furthermore, the 9801 provides several protection features: overvoltage (OVP), overcurrent (OCP), overpower (OPP), and overtemperature (OTP) protection, settable voltage and frequency limits, key lock function, and RMS/peak current protection settings to shut off the output when a load exceeds the set current.

B&K Precision’s 9801 AC power source costs $1,995.

The series includes four 200- to 600-W models that can deliver power in any combination of the rated voltage and current up to the maximum output power of the supply. With voltage and current ranges up to 150 V and 25 A, the programmable DC power supplies are well suited for electronics manufacturing, R&D, and more.BK-9201_front

 

Multi-range power supplies provide greater flexibility than traditional power supplies. The supplies can provide any combination of higher voltage or higher current along a maximum power curve. This design helps save both bench space and cost by eliminating the need for having multiple power supplies on your workbench.

 

On the front panel, the 9200 Series features a high-resolution, 1 mV/0.1 mA display, output on/off control, and a handy user interface with numerical keypad, cursor keys, and rotary control knob for adjusting voltage and current settings. The power supplies also provide internal memory storage to save and recall up to 72 different instrument settings.

 

For programming and remote control, the 9200 Series offers list mode programming, remote sense, and standard USBTMC-compliant USB, RS-232, and GPIB interfaces supporting SCPI commands. Remote control software is provided for front panel emulation, execution of internal and external program sequences, and logging measurements via a PC.

B&K Precision Rejuvenates Arbitrary/Function Waveform Generator Line

B&K Precision announced that it rejuvenated the 4075B Series of arbitrary/function waveform generators with higher frequency ranges, increased arb memory, and a color LCD. The new 4075B Series offers six new models that directly replace the previous 4075 line with single- and dual-channel 30-MHz (4075B/4078B) and 50-MHz models (4076B/4079B) along with two additional single- and dual-channel 80-MHz models (4077B/4080B). Each model can generate arbitrary waveforms with 14-bit amplitude resolution, a 200-Msps sample rate, and up to 16,000,000 points (depending on model). These instruments are ideal for use in electronic design, sensor simulation, and functional test.4075B_front

Designed with a dual technology architecture, the 4075B Series combines the benefits of traditional DDS (direct digital synthesis) technology and a true AWG (arbitrary waveform generator). DDS allows standard sine, square, and triangle waveforms to be generated with great frequency resolution at a low cost while the true AWG architecture implements custom arbitrary waveforms with a point-by-point design. This design significantly minimizes jitter and improves signal integrity of the arbitrary waveform.

Similar to their predecessors, the new 4075B Series generators offer a menu-driven front panel keypad with rotary encoder knob and convenient range selection buttons to make adjustments quickly and easily. Additionally, all models provide multi-unit/channel synchronization and external triggering capabilities. For precise triggering at specific points in an arbitrary waveform, users can benefit from the instrument’s fully programmable markers, which allow the unit to generate a positive TTL level signal at a specified waveform address.

The 4075B Series provides eight full memory banks per channel for user-defined arbitrary waveforms and 49 locations to store/recall instrument settings. Arbitrary waveforms can be created from the front panel or loaded using B&K’s free WaveXpress waveform editing software. WaveXpress is a comprehensive stand-alone application that offers several waveform editing tools for users to easily create and load complex arbitrary waveforms onto the AWG via the SCPI-compatible USBTMC or GPIB (50 and 80 MHz models only) interface on the rear.

Other features of the 4075B Series include AM/FM/FSK modulation schemes, linear and logarithmic sweep, and built-in overvoltage and short circuit protection for resistive and capacitive loads on all inputs and outputs to prevent accidental damage to the instrument.

Available immediately, B&K Precision’s 4075B Series products are all backed by a standard 3-year warranty and listed at the following prices ranging from $1,495 (Model 4075B) to $3,690 (Model 4080B).
