1.0 INTRODUCTION
Important: Read Section-2 before attempting to use your analyzer --
applying
incorrect
operating
voltages
could
result
in
permanent
damage!
Also, never apply a DC voltage to the antenna connector.
General Description: The MFJ-213 is a self-contained handheld RF
analyzer that performs the following diagnostic functions:
SWR (1:1 to 9.9:1)
Complex Impedance (Z = R + jX)
Impedance Magnitude (Z in Q)
Return Loss (in dB)
Cable Loss (in dB)
Capacitance (in pF)
Inductance (in uH)
The MFJ-213 also generates a 0-dBm RF signal that may be used to check
receivers, networks, amplifiers, and antenna patterns. Operating range is:
HF: 1.00 — 60.00 MHz
The
MFJ-213
uses
a
DDS
signal
generator
giving
a
stable
0dBm
signal
tuned
by a rotary
encoder.
Measurements
are displayed
on an easy-to-read
LCD
screen
with
optional
backlighting.
Power
is supplied
by internal
AA cells,
an
18650
Li-ion
cell or by a regulated
12-VDC
external
power
source
(not
included).
Weighing
just
over
1.3 pounds,
the MFJ-213
package
fits
comfortably
in one hand
for convenient
bench
work
or on-the-fly
testing
in
the field.
Operation
is simple,
but you will need
to read
the manual
to learn
all of the unit's
features
and
functions.
The
more
you
know
the more
valuable
it will become
as a diagnostic
tool.
