Tere.
Sellise isendi ebays : Amplifier Research 15S4G8A Microwave Amplifier, 4 - 8 GHz, 15W
Kas tõesti maksab see asi nii palju ?
Pole just nendes asjades kõigeteravam pliiats aga ikkagi tundus ulme.
Ärge siis kohe peksa andke. :lol:
Aga kui keegi oskab lahti seletada miks see asi niipalju maksab, siis oleks uudisimu rahuldatud :?:

Panen siia lingi ja väikese tutvustuse ka.

Müügi hind Ebays on 24,750.00 $
Posti maks Eestisse 2,103.05 $

Selline lühitutvustus ka :

Amplifier Research 15S4G8A Microwave Amplifier, 4 - 8 GHz, 15W

DESCRIPTION


The Amplifier Research 15S4G8A is a self-contained,
air-cooled, broadband amplifier designed for applications that require instantaneous bandwidth and high gain.
It is housed in a stylish cabinet and designed for benchtop use,
but can be removed for equipment rack mounting.

Features and Specifications of the Amplifier Research 15S4G8A Amplifier include:
•Features:
◦Provides a minimum of 15 watts of RF power when used with a sweep generator
◦Front panel gain control provides convenience of setting desired output level
◦RF input leveling circuit:
◾Protects the amplifier from RF input overdrive
◾Controls RF input level to the RF amplifier first stage when RF input level is increased above 0 dBm
◦RF amplifier stages are protected from over-temperature, due to cooling blockage or fan failure, by removing the DC voltage to them
◦Digital Display on front panel indicates operate status and fault conditions when over-temperature or power supply fault occurs
◦Digital control for both local and remote control of the amplifier
◦Control System is a 16-bit RISC microcontroller board:
◾Handles primary functions of the amplifier
◾Interprets commands sent to it from an 8-bit remote interface board:
◾8-bit microprocessor controlled board provides IEEE-488 (GPIB) and RS-232 control of all amplifier functions
◦Expandable power technology provides upgradability
•Specifications:
◦Rated output power: 15 watts minimum
◦Power output @ 3dB compression:
◾Nominal: 19 watts
◾Minimum: 16 watts
◦Power output @ 1dB compression:
◾Nominal: 16 watts
◾Minimum: 14 watts
◦Flatness:
◾typical: ±1.0 dB
◾maximum: ±2.0 dB
◦Frequency response: 4.0 – 8.0 GHz instantaneously
◦Input for rate output: 1.0 milliwatt maximum, 0 dBm
◦Gain (at maximum setting): 42 dB minimum
◦Gain adjustment (continuous range): 10 dB minimum
◦Input impedance: 50 ohms, VSWR 2.5:1 maximum
◦Output impedance: 50 ohms nominal
◦Mismatch tolerance:
◾100% of rated power without foldback
◾Will operate without damage or oscillation with any magnitude and phase of source and load impedance
◦Modulation capability: Will faithfully reproduce AM, FM, or pulse modulation appearing on the input signal
◦Harmonic distortion: Minus 20 dBc maximum at 15 watts
◦Third order intercept point: 51 dBm typical
◦Noise figure: 10 dB typical
◦Primary power (selected automatically):
◾90-132, 180-264 VAC
◾50/60 Hz, single phase

◦Connectors:
◾RF:
◾Input: Type N female on front panel
◾Output: Type N female on front panel
◾Remote Interfaces:
◾IEEE-488: 24 pin
◾RS-232: 9 pin subminiature D (female)
◾RS-232 (Fiber-optic): Type ST
◾USB 2.0: Type B
◾Ethernet: RJ-45
◦Safety Interlock: 15 pin subminiature D
◦Cooling: Forced air (self contained fans)

Tegu on laborivõimendiga või siis arusaadavamalt väljendades - laboris kasutamiseks mõeldud täppismõõteriistaga.
Sagedusala mängib ka rolli,kuid peamine on siiski otstarve - läänes maksavad korralikud laboripillid ikka omajagu.
Lisa sinna juurde veel korralikud liidesed andmevahetuse korraldamiseks mõõtesüsteemis GPIB (IEEE-488), fiiberoptiline
järjestikport jne ja hind ei tulegi enam ulme. Samas on see vananenud mudel ja on pandud veel odavama hinnaga müüki ka.
