MeasuringVSWR panoramic R2-102 (R2102, R2 102)
Designed for a panoramic display on the display screen and measure the frequency characteristics of VSWR and attenuation coaxial elements tract.
Frequency range 0.01 GHz to 2.14GHz.
The structure of measurer R2-102 includes:
- a display unit Ya2R-70;
- generator unit sweep frequency - Ya2R-74.
Measuring VSWR panoramic R2-102 intended for panoramic display the indicator and measuring the frequency characteristics of VSWR and attenuation elements coaxial tract.
MeasuringVSWR panoramic R2-102 is designed for use in laboratory and shop floor, as well as repair shops and verification bodies at an ambient temperature of 5 to 40 ° C, relative humidity of 98% at 30 ° C and can be stored at a temperature of minus 55 to 50 ° C.
Operating conditions under which a basic error of devices Measuring VSWR panoramic R2-102
1) supply voltage, V 220 ± 4,4;
2) the relative humidity,% (30 - 80);
3) ambient temperature, ° C 20 ± 5.
The device has to work with a shared channel (CPC) and the automated measuring system (AIS). To do this, set the indicator has an external interface CPC.
MeasuringVSWR panoramic R2-102 paths have the following measurement and frequency ranges listed in Table 1.
Measurement range and the maximum permissible error of measurement for Fst VSWR ≤ 2 should be as given in Table 2.
Measuring range and limit the margin of error measuring the attenuation of passive two-ports with Fst u ≤ 1,2 should be as given in Table 2.
Maximum permissible error for measuring VSWR Kstu from 2 to 5 (δKstu 2) is defined by:
δKstu 2 = (± δKstu 1) / (100 - (± δKstu 1) δKstu 1 / (1 + δKstu))
where δKstu 1 - Accuracy Kstu for VSWR ≤ 2; Kstu - measured VSWR.
where A - the measured attenuation in decibels; Kstu - measured VSWR.
In the device provides the following modes of frequency tuning:
1) manual frequency tuning;
2) manual sweep;
3) an automatic sweep with a duration of periods of 0.08, 1;
4) single sweep with a duration period of 10 s and manual start.
The maximum oscillation frequency band of not less than the working frequency range of the instrument measuringVSWR panoramic R2-102. The minimum frequency swing should be no more than 0.5% of the upper frequency range.
Maximum permissible error count and set the frequency of ± 3 MHz to 0.6 GHz and a maximum of ± 0,5% from the current frequency above 0.6 GHz.
On the CRT screen shows two amplitude frequency tags. Via 1 - directed upwards, the channel 2 - directed downward. The limits of acceptable errors in the measurement of VSWR and attenuation in the operating ambient temperatures from 5 to 40 ° C for a maximum value of basic error.
Measuring VSWR panoramic R2-102 provides its specifications within the rules at the end of a setup time of 15 minutes.
Instruments allow continuous operation under the operating conditions for a time at least 16 hours while maintaining their performance.
Measuring VSWR panoramic R2-102 retains its specifications when powered from an AC voltage (220 ± 22) V (50 ± 0,5) Hz.
The power consumed by the device from the power supply at rated voltage does not exceed:
1) to sweep YA2R-74-75 YA2R, YA2R-76/2 - 100 VA, 2) for the indicator - 80 VA.
The device provides the interface functions in accordance with the Table. 3.
Mean time between failures (To) but less than 7,000 hours Gamma-percent life of at least 10,000 hours at γ = 90%. Gamma-percent service life of at least 10 years at a value of γ = 90%. Gamma-percent storage life of at least 10 years for heated storage or 5 years for unheated storage at γ = 80%.
Mean time to repair less than 8 hours no chance of latent failures of at least 0.9 for the calibration interval 18 months., With the utilization factor Ki = 0.12.
