1.1 Features
The "
FRA 51602 GAIN-PHASE ANALYZER
" measures the loop gain frequency characteristics of
circuits such as inverters and switching power supplies by frequency sweeping. The instrument has a sweep
oscillator that uses the synthesizer method for driving the circuit being measured, an analyzer for
measuring the response of the circuit being measured to the driving signal and obtaining gain and phase
data, and a display screen for presenting the results. In addition to measuring the loop gain of inverters,
switching power supplies, and DC-DC converters, and mechanical servo characteristics, the instrument can
also measure the gain-phase characteristics of electronic circuits.
(1) High accuracy and wide dynamic range
The internal oscillator of the instrument maintains high frequency accuracy and resolution by using the
synthesizer method. The analyzer ensures a wide dynamic range with a high-resolution A/D converter and
an automatic ranging function.
(2) Isolated input and output connectors
The two analysis inputs and oscillator outputs are independently isolated from the instrument enclosure
(600 V CAT II/300 V CAT III).
(3) Wide frequency range (10 µHz to 2 MHz)
This instrument can measure across a 10 µHz to 2 MHz frequency range with a single sweep.
(4) Color LCD and touch panel
The frequency characteristic graph and measurement condition setting menu are displayed on a color LCD
that is equipped with a touch panel. Various settings and operations can be performed intuitively by
touching the screen.
(5) High-speed measurement (as fast as 0.5 ms per data point)
Frequency sweeping is performed at up to 0.5 ms per data point. This performance contributes to
shortening the Takt time.
(6) GPIB/USB/RS-232/LAN interface as standard equipment
It is possible to set measurement conditions and read measurement data with an external personal computer.
