Thank you for viewing this auction! Up for auction is a used Boonton RF Power Meter, Model 4220 & Power Sensor, Model 51011 (4B) with connecting cable. Cosmetically all of these items are in excellent condition; however, I do not know if they are operating properly as I have no way of testing them. These items are being sold AS IS! What you will receive… Boonton 4220 RF Power Meter AC Power Cord 4220 Instruction Manual (copy; covers installation, operation, application notes, theory of operation, maintenance, schematic diagrams, and a parts list) Boonton 51011 (4B) Power Sensor Power Sensor Connecting Cable The Model 4220 is a microprocessor-based, single channel, solid state RF powermeter. It is capable of measuring RF power levels from -70 dBm to +44 dBm. The frequency range and power level are sensor dependent. The Model 51011 Power Sensor is a diode sensor that measures voltage across a precision resistor, using specially selected diodes. Detection is square law (true RMS) over approximately the lower two-thirds of the sensor dynamic range, and peak detecting over the upper portion. In the RMS region, linearity is excellent, and any signal type can be measured Some of the specifications for the 4220 Power Meter are as follows: Frequency Range: 100 kHz to 100 GHz, sensor dependent Power Range: -70 dBm to +44 dBm. sensor dependent Power Sensors: Compatible with all Boonton diode and thermal sensors Dynamic Range: Up to 90 dB with diode sensors Up to 50 dB with thermal sensors Displays: Main Data: 4-1/2 digit LED dB CAL FACTOR: 4 digit LED Analog: Meter, reading proportional to main data display (fs=10dB; ±5dB in dBr) Display Units: W, mW, µW, nW, dBm, dBr Display Resolution: 0.01 dB or 4-1/2 digits Power Requirements: 100, 120, 220 or 240 VAC, 50-60 Hz or 400 Hz, 40 VA Max Weight: 6.6 pounds Dimensions: 3.5” high x 8.25” wide x 13.25” deep Some of the specifications for the 51011 (4B) Power Sensor are as follows: Frequency Range: 100 kHz to 12.4 GHz PWR Range (Watts & dBm): 1 nW to 100 mW -60 to +20 dBm Overload Rating (Watts & dBm): 300 mW +25 dBm Maximum SWR: 100 kHz to 2 GHz Max SWR = 1.12 2 GHz to 4 GHz Max SWR = 1.2 4 GHz to 11 GHz Max SWR = 1.4 11 GHz to 12.4 GHz Max SWR = 1.6 EEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE SHIPPING: I will ship to locations in the U.S. and internationally (see below).
