TSPECIFICATIONS
The NS-660/660P is a high quality instrument with unique features
which make tedious measurements of SWR and Power during antenna
tests, matching and tuning of transmitters a very easy task.
SWR and Power indicators are installed in one meter unit. One
scale will indicate Forward Power, another scale Rellected Power
and SWR is indicated at the crossing point of the 2 needles. This
unique feature makes it possible to read Forward Power, Reflected
Power and SWR all at the same time.
The meter unit has built-in illumination which provides improved
readability. ln addition to the built-in RF power sensor, an optional
remote sensor can be used via EXT Sensor socket on the rear panel.
The NS-660P can also measure PEP Peak Power in SSB operation.
X To connect with NS-660/660P, remote sensor units (U-66H,
U-66V and U-66S2), sensor changeover switch (SS-2), and
extention cable 20meters (SC-20) are provided separately.

IOPERATION
AVG lndicates RMS power of FM or continuous wave signal and
SWB.
NORMAL : lndicates approximate average Peak Power ol SSB signal.
HOLD : lndicates maximum Peak Power of SSB signal.
(Battery, OO6P gv,or DC power must be connected for meter to function
PEP operation.)
(1) Select the Mode switch to "AVG" position.
(2\ Please refer to OPERATION of NS-660 series meters._.
t) Measuring PEP power
(1 ) Connect the DC power socket to a DC power supply (6-24V) using
the cable provided.
(2) Turn the Mode switch to either "NORMAL" or "HOLD" positlon.
(3) When the transmitter is operated and the switch is in the
"NOBMAL" position the meter needle indicates average PEP of the
SSB signal. ln the "HOLD" position the true maximum PEP is
indicated.
x ln the "NORMAL" and "HOLD" positions while measuring forward
PEP, there is no indication of reflected power.
x During the various SSB transmission modes, as shown in the table
left, the meter reading of AVG and PEP will differ. Therelore, when in
the SSB transmit mode, before switching the mode switch from AVG
to PEP (NORMAUHOLD), make certain that the meter power setting
is correct. Otherwise, the meter needle will go off-scale, resulting in
damage to the instrument.
T CAUTIONS
X The meter movements are highly sensitive. Prevent mechanical
shock and vibration.
Measuring power with a poorly matched antenna or disconnecting the
output ol the bridge while operating may damage the meter.
Do not leave the meter lamp on if the meter is powered by battery.
Weak battery may cause measuring error or other malfunctions.
Reset meter needle by changing the Mode switch to the "NOBMAL"
and back to "HOLD" position il you wish to use the HOLD posilion
repeatedly. (NS-660P only)

o Use only soohms coax line for connections. This will maintain the
accuracy of the mater.
oFor accurate power measurements, use soohms pure resistance

o"Fouard" scale indicates Forward Power.
o "Reflected" scale indicates Reflected Power.
o Effective Radiated Power.
To measure effective radiated power, subtract Reflected power
from Forward Power.(Apparent loss is only produced by impedance
mismatch and does not include cable losses.)
