![]() | ||
Frequency Range | The frequency range that devices can measure. | ||
Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
![]() | |||
dBm Measurement Range | The maximum dBm power that devices can measure. dBm = 10 log (P/Pref), where P is the measured power and Pref is the reference power (1 milliwatt). | ||
Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
![]() | |||
Power Range | The meter measures the real power (active power) range that devices can measure. | ||
Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||

![]() | ||
Features | |||
Your choices are... | |||
Adjustable Sampling Rate | The sampling rate is manually adjustable. | ||
Alarm LED | Alarm light-emitting diodes (LEDs) light when the RMS value or peak value is greater than the range. Typically, alarm LEDs light only when the range has been greatly exceeded. | ||
Application Software | The device has embedded application software. | ||
Auto-Ranging | Auto-ranging devices are self-adjusting to offer the best measurement scenario. | ||
Battery Powered | Devices are battery-powered. | ||
Data Acquisition | Devices with data acquisition capabilities have a computer interface and software for uploading data. | ||
Data Storage / Logging | Data storage or data logging devices have internal memory for storing data. | ||
dB Readings | Devices measure values in decibels (dB). | ||
External Shunts | External shunts can be used to extend the current input range. For example, an input that exceeds 5 A can be measured by providing a shunt. | ||
Filters | Devices have embedded filters. | ||
Integrating Functions | Integrating functions allow the active power and current to be integrated (Wh and Ah). | ||
Mirrored Scale | Mirrored scales make it easier to read the instrument to a given accuracy by enabling the operator to avoid parallax errors. | ||
Overload Protection | Devices with overload protection have fuses or other devices to protect the meter. | ||
Programmable | Programmable devices can be programmed with trigger values to perform measurements. | ||
Range Switch | Range switches can be used to select an appropriate range of units to be measured. | ||
Removable Data Storage | Devices with removable data storage have removable memory, drives, etc. | ||
Scaling Function | Devices with a scaling function allow the pre-setting of the potential transformer and current transformer ratio, and the power scaling factor. | ||
Temperature Compensated | Temperature-compensated devices are designed to counteract known errors caused by temperature changes. | ||
Triggering | Devices with triggering have an interface for external triggering. | ||

Output Interface | |||
Your choices are... | |||
GPIB | The general-purpose interface bus (GPIB) is designed to connect computers, peripherals and laboratory instruments so that data and control information can pass between them. It was originally developed by Hewlett Packard (HP) and called the HPIB bus. GPIB is also known as the IEEE 488 bus, and is electrically equivalent to the IEC 625 bus. | ||
USB | Universal serial bus (USB) is a 4-wire, 12 Mbps serial bus for low-to-medium speed peripheral device connections to personal computers (PC), including keyboards, mice, modems, printers, joysticks, audio functions, monitor controls, etc. The USB design is standardized by the USB Implementers Forum (USBIF), an organization that includes leading companies from the computer and electronics industries. The current USB specification is USB 2.0, which supports data transfer rates of up to 480 Mbps. | ||
RS232 | RS232 is a serial interface approved by the Electronic Industries Association (EIA). RS232 uses two-way transmissions and is common in low-end professional and consumer equipment. | ||
BCD | Binary coded decimal (BCD) is a circuit code which represents decimal numbers in binary code. With BCD, each decimal digit is represented by the four-bit binary representation of the digit. | ||
D/A | The output interface is digital-to-analog (D/A). | ||
Other | Other unlisted interfaces. | ||
