Microvoltmeter SMV 11 (SMV-11, SMV11, СМВ 11, СМВ-11, СМВ11)
Is used for selective high-frequency sinusoidal voltage measurements - (from -20 dB mkV to +125 dB mkV).
The device measures the figurative impulsive voltage noise of the following types:
quasi-peak value «QP», the peak value «P», the effective value «RMS».
Has an output for generator Ri = 50Ohm, EMF = 100 dB mkV.
Selective microvoltmeter SMV11 is single band frequency receiver in a range from 9 kHz to 30 MHz. It is designed for selective measurements of high-frequency sinusoidal voltage and quasi-peak figurative impulsive voltage noise measurements.
It is used as an radio interferencemeasuring instrument and it meets the requirementsof MSKRContent-I recommendations and the conditionsdevelopedon thesestandards, such as CEB - CT -CEB -502, GDP - TGL 20 885 l. 2
Selective microvoltmeter SMV11 is adapted for ordinary selective voltage measurement in a range from -20 dB mkV to +125 dB mkV, without any additional accessories. Its high dynamic selectivity and sharp intermediate frequency filters provide measurement of low-voltages near strong external signals. 7 types of indications, 3 high frequency bandwidths and a number of measuring outputs, makes the signals measuring process much easier. The device measures thefigurative impulsivevoltagenoiseofthe following types: quasi-peak value («QP»), the peak value («P»), the effective value («RMS»). The receiver is automatically poweredinto optimaloperating condition by an internalprogram for alltypes ofindications.
Microvoltmeters SMV11 have a generator output Ri = 50 0hm; emf = 100 dB mkV. It is possible quickly and easily to measure the active and passive quadripole without any additional device, due to large dynamic range, generator frequency equation and received signal frequency. Generator Output can replace an additional measurement transmitter, in many measurement assignments (for example, when measuring reflection coefficient).
Receiver’s selective sections are switching automatically with indicated frequency, but they can switch off if necessary. Selective microvoltmeter SMV11 can be also used for frequency-analytical tasks with the help of external oscillatory signal and suitable visual output device.
Microvoltmeter SMV11 and field strength measuring antenna FMA 11 form a FSM 11 set, for radio interference measurements.
This measuring set as basic device corresponds to MCKP conditions and standards, developed on their base for radio interference measurement technique. Antenna is designed in such way that field components can be optionally defined as with the help of frame or whip antennas. Switching of broadband transmission circuits in antenna are carried out remotely from receiver. This greatly simplifies field strength measurement.
If selective microvoltmeter SMV11 is combined with equivalent network NBB12 or NBB 13, they form measurement set for voltage disturbances measuring regulation that arise in electrical appliances supply.
Together with probes TK 11 and TK 12 high-voltage networks interference measurement is possible.
Current measurement probes expand selective microvoltmeter SMV11 to a measuring set for regulated measurement of current interference in networks. The main area of microvoltmeter SMV11use with mentioned accessories is measuring interference technique in accordance with existing regulations. The main consumers are industry and governmental organizations for compliance regulations and electromagnetic compatibility control of devices and systems.
Microvoltmeter’s SMV11 diversity as a selective voltage measuring instrument with generator output, makes it a rational device in quadripoles measurement in laboratories and test benches.
Together with measuring antennas, the use of microvoltmeter SMV11 extends to distribution and supply measurement, antennas and radio control, for assignments in german post office, in transport facilities, radio and television facilities and in commercial radio.
Microvoltmeter SMV11 is immediately ready for use and saves its settings in difficult woring conditions such as high air humidity, freezing temperatures -25 ° C, external electromagnetic fields. Power supply can be selectively carried out by network and battery.
