RF MICROWAVE MEASURING INSTRUMENTS

ELECTRONIC VOLTMETER

The ML69B is a high-sensitivity, high-frequency electronic voltmeterusing semiconductor diodes and a high-sensitivity chopper amplifier. It can measure high-frequency voltages ranging from 10 kHz to 1000 MHz with a full-scale sensitivity of 1 mV. It has a pen-type Probe MA61B, which can measure at high impedance with minimal effect on the device under test.

INTERFERENCE/FIELD STRENGTH METER

The ML428B not only enables measurement of the field strength ofgeneral broadcasts and radio communications, but it can also perform measurements of interference waves in accordance with CISPR, VDE,FCC, or other specifications. The ML428B possesses a local syn- thesizer and high-precision sine-wave comparison oscillator to obtain data with excellent repeatability. In addition, the built-in microproces- sor allows level calibrations and attenuator operation to be automat- ically performed to enable direct reading of the field strength and ef- ficient measurement.

ML428B

9 kHz to 30 MHz For Measuring Noise Field Strength (in Conformance with CISPR Specifications)

Features?

Correct interference measurement can be performed in accordancewith CISPR specifications.

?

The use of a frequency synthesizer in the local oscillator enables ahigh degree of frequency stability to be gained.

?

Allows direct reading of the field strength.

?

Up to a maximum of any 100 frequencies can be stored.

?

Prompt measurement is possible through use of the auto-rangefunction.

?

Direct readout of field strength is possible arbitrarily for conventionalantenna by memorizing its coefficient via GPIB.

?

Convenient outdoor operation through the use of a DC power source.

GPIB RESISTANCE ATTENUATOR

These are variable resistance attenuators for measurement of 50 Ω

MN510C/D

(MN510C) and 75 Ω (MN510D) impedance systems. Each of theseattenuators has a wide frequency range and is highly accurate, com- pact, lightweight with good articulation, and easy to handle. Moreover,comparison measurement can be made far more smoothly whenused in conjunction with a key box.
