FOR AUCTION: Selective microvoltmeter(receiver) STV-301-2 made by RFT. Specifications: Selective transistor microvoltmeter STV 301-2 Also, this device can be called: STV301-2, STV-301-2, STV 301 2, STV3012, STV 3O1-2. STV 301-2 selective microvoltmeter - sensitive heterodyne receiver with access to a pointer instrument and headphones. STV 301-2 used to measure high voltages and useful radio (pulse sequences are evaluated by subjective perception of hearing). Specifications STV 301-2: Frequency range - 0,15 MHz to 30 MHz. Intermediate frequency - 110 kHz; 1,7 MHz. Error of frequency at ambient temperature: - From -5° C to +50° C - no less than 3%; - From -30° C to - 5° C - less than 5%. The bandwidth of single signal - to 5 MHz. Sinusoidal voltage: - With respect to 1 mV - from -3,7 dB to 90 dB (0,65 mV to 30 mV); - With a removable divider 20 dB - from 16,3 dB to 110 dB (6,5 mV to 300 mV). Quasi-peak measurement of pulse voltage noise for the repetition frequency of 100 Hz: - With respect to 1 mV - from -3,7 dB to 80 dB (0,65 mV to 10 mV); - With a removable divider 20 dB DGF / dB 8 - from 16,3 dB to 100 dB (6,5 mV to 100 mV). Voltage ratio: - Norm - from 0 dB to 90 dB; - With a removable divider 20 dB DGF/8 dB - 20 dB to 110 dB. Input impedance microvoltmeter STV 301-2 - from 60 Ohm to 90 Ohm. Limit scale: - Sinusoidal voltages - from -16 dB to +4 dB; - Switching voltage - from -10 dB to +4 dB. Impulse response frequencies, respectively: - 10 Hz - (-10±2,5 dB); - 20 Hz - (-6,5±2 dB); - 100 Hz - 0 dB; - 1000 Hz - 4,5±1,5 dB. Measurement error sinusoidal voltages - ±4 dB (optional - not more than 0,3 mV). Maximum input voltage STV 301-2: - Permanent - 63 V; - Variable (with frequency - 400 Hz) - 42 V. Bandwidth microvoltmeter: - Norm - 9 kHz±1 kHz; - 6 dB - 3 kHz. Clarifier for selectivity 60 dB - not less than 25 kHz. Stability with respect to undesired displacements results (weakening points spurious reception channels) - not less than 30 dB. Attenuation: - Intermediate frequency - not less than 30 dB; - Mirror channel - not less than 20 dB. Shielding effectiveness STV 301-2 - not less than 20 dB. Calibration voltage pulse generator using the built throughout the frequency range. Low frequency output for headset - 4 Ohm. Connection for additional devices - 12 V, max. 5 mA to the front panel. Input - RF connector hulled 75-0-f1. Mass - 7 kg. Dimensions - 360x130x320 mm. Operating conditions STV 301-2: Food: - From - 220 V; Power consumption - 5 V•A.
