Features And Functions - microHAM SMORF Manual

SMΩRF™ is unique metering instrument, the most powerful and accurate, in-line vector RF power meter to date
with accuracy rivaling the professional instruments. Has tons of extra features, and very high level of user
customization to fit every hamshack, every operator's needs.
SMΩRF™ connects to RF signal by remote sensor (coupler), available in several models for power levels from
miliwatts up to 12kW and frequencies up to 500MHz. HF + 6m sensors provide sample of passing current (I) and
voltage (U) on its LOAD port. VHF and UHF sensors provide sample of forward (FWD) and reflected (REF)
power to meter. The meter can simultaneously measure two independent signals from any two sensors and
shows measurement results on its front panel or computer.
Main features:
Operating frequency from 1.8 – 500MHz.
•
Signed phase measurement.
•
Two points of measurement, at the sensor point and at the antenna point.
•
Phase measurement between sensors.*
•
Real time temperature compensation in meter and sensor.
•
Dual, high speed, three color, user adjustable auto-ranging LED bar graphs with configurable peak hold.
•
Every meter and every sensor individually factory calibrated for best accuracy. Temperature controlled,
•
computer automatized calibration setup makes over 10,000 calibration points in each meter and over 100
points in each sensor. Calibrated per port for level, frequency, phase, and temperature.
Very wide viewing angle, sunlight readable, high contrast graphics OLED display.
•
Multiple, user configurable display screens for powers, impedance, waveform, spectrum, PSK, SO2R ...
•
User configurable alarms in three importance levels (warning, alarm, fault) for two power ranges on per
•
sensor, per band basis for SWR, Low Power and High Power alerts.
Connectivity:
Internet enabled, native IEEE 802.3 Ethernet port for remote connectivity.
•
Internal web server for simple access from the computer browser for status checking, maintenance and
•
firmware updates, no drivers, no specialized software installation.
TCP port for high speed remote control applications, open protocol.
•
High purity, DDS based test signal generator (single/dual tone, noise) for linearity and bandwidth tests.
•
iLINK port for simplified connection to our interfaces.
•
Two keying, pass thru ports and RS232 serial port for legacy connections.
•
Well featured Auxiliary port for future expansions (wall mount 7 segment LED displays, analog meter).
•
Other features:
Internal speaker for audible alerts.
•
Internet synchronized real time clock.
•
Ambient light sensor for display and led bars brightness control.
•
Free Remote Control application for Windows and OS-X.
•
EMI shielded, aluminum die cast enclosure.
•
Internal processing highlights:
210 MIPS, 32bit floating point Cortex M4 DSP processor for extremely fast updates and accurate
•
calculation of complex functions.
hi-grade, parallel 16bit ADC, sampled at 125ksps.
•
24bit DAC at 160ksps for signal generator.
•
*
Both sensors are of the same type (U/I or FWD/REF), connected by the same length leads and operating at the same frequency.
