Zn1181H Dow Frequency power signal generator (1M-180M)

First, overview The Zn1181H dot frequency power signal generator is a power signal source consisting of 1 MHz, 5MHz, 10 MHz, 20 MHz, 30 MHz, 42MHz, 63 MHz, 100 MHz, 130 MHz, 180 MHz, and power amplifier. It uses a device that makes into a transmitter with a distributing antenna, which is suitable for measuring the shielding performance of the shielding device, especially suitable for the test and detection of nuclear magnetic resonance chamber shield. It has the advantages of a wide range of energy range, simple, easy to carry, and efficient performance, and high frequency accuracy. It is possible to use the factory, defense, laboratory, and scientific research unit. Second, work characteristics 1. This instrument can work for 8 hours in the following environments: Temperature: 0 ° C ~ 40 ° C; Relative humidity: 80% (40 ° C); Atmospheric pressure: 86 ~ 106kpa; Power supply voltage: 220V ± 10%, 50Hz ± 2Hz; No corrosive gases around, no strong electromagnetic field. 2. Frequency: Total 10 1MHz ± 1 × 10-5 5MHz ± 1 × 10-5 10MHz ± 1 × 10-5 20MHz ± 1 × 10-5 30MHz ± 1 × 10-5 42MHz ± 1 × 10-5 63MHz ± 1 × 10-5 100MHz ± 1 × 10-5 130MHz ± 1 × 10-5 180MHz ± 1 × 10-5 3.
