Diamond SX-200/SX-400 standing wave uses a method than powermeter

SX - 200 / SX - 400 standing wave compare powermeter is Japan of company limited of industry of the first electric wave " diamond antenna " series product, it is a kind of passive standing wave compares powermeter, it join is between broadcasting station and antenna, through simple operation line of make a present of of emissive power of measurable broadcasting station, antenna and broadcasting station do not match the reflection power that cause and standing wave to compare, this powermeter in communication of this explicit odd webbing still can include monitor of power of subsidiary channels in the human body through which vital energy as peak value. This appearance serves as telegraphic, legionary, railroad (wireless overhaul place) the commonly used appearance that waits for wireless communication branch is used extensively, because operation instruction handbook is Japanese, read inconvenience, to facilitate spot personnel is used correctly, be as follows use method and note introduction now.

1 appearance expresses function of head, switch, port

Position of appearance watch head, switch, port sees a picture 1

① expresses a head: The peak value when be being used at the directive to launch power, reflection power, standing wave comparing and unilateral belt to apply includes the numerical value of power of subsidiary channels in the human body through which vital energy.

5 scale are shared on watch head. From go up downward, the 1st, 2 scale are worth than scale for standing wave, mark has on the right side of the first path scale " H " , when broadcasting station outputs power to be more than 5W, should read from this scale take standing wave specific value; Mark has on the right side of the 2nd path scale " L " , when broadcasting station outputs power to be less than 5W, should read from this scale take standing wave specific value; The 3rd, 4, 5 scale are worth scale for power, part archives of 200W of full span of corresponding power worth, 20W, 5W.



Switch of ② RANGE(span

Choice power measures span, in all 3 archives, it is 200W, 20W, 5W respectively.

③ FUNCTION(measures functional select switch

Park " POWER " when, undertake emissive power (power of FWD) , reflex (REF) is measured.
'
Park " CAL " when, undertake standing wave is compared (the calibration before SWR) is measured.

Park " SWR " when, undertake standing wave is compared (SWR) is measured

Knob of ④ CAL(calibration)

Undertake standing wave is compared (before SWR) is measured (be measured broadcasting station is in the) below emissive condition, undertake calibration with this knob, should move hand watch head mark has on the right side of the first scale "  " place.

⑤ POWER(power measures select switch

Park " FWD " when, undertake broadcasting station emissive power is measured.

Park " REF " when, undertake wave power is measured reflexing.

Park " OFF " when, stop pair of broadcasting station the measurement of all sorts of power.

Average of ⑥ AVG, PEP MONI(or power of sth resembling a net of peak value bag measure select switch) when   measures emissive power, reflection wave power, standing wave to compare, this switch should bounce, show " ■ " condition, the average that expresses head institute to show those who show is power right now (AVG) .

Include power of subsidiary channels in the human body through which vital energy as odd webbing peak value (when PEP MONI) monitor, this switch should press, show " ━ " condition.

⑦ adjusted bolt at 0 o'clock

Use at expressing the mechanical zero of head finger, this bolt is adjusted to be able to make pressing with a finger indicates null before measuring.

⑧ TX(and broadcasting station catapult are linked together port) can refer to a graph at the same time 1 reach a figure

Carry this port and broadcasting station antenna with 50 Ω coaxial cable (ANT) is linked together.

The port of join of line of day make a present of that ⑨ ANT(and broadcasting station use)

The line of make a present of that uses broadcasting station actually line of day make a present of (50 Ω ) port
