GB/T3789.1 General principles for the test method of the electrical performance of transmitting tubes GB/T3789.14 Test method for the electrical performance of transmitting tubes Test method for static characteristic curve 3 Terminology
Static characteristic reference point static characteristic tefetence point The static characteristic reference point refers to a point on the electron tube anode current-first gate voltage characteristic curve. This point refers to the first grid voltage value when the anode current reaches the specified value under the electrode voltage state specified in the detailed specification. 4 Power supply schematic
Test equipment and test rulesbzxZ.net
The test equipment and test rules should comply with the provisions of GB/T3789.1. 6 Test method
6.1 Add the filament voltage and each electrode voltage according to the specification, and add enough negative voltage to the first grid to make the tube under test in the cut-off state. Approved by the State Administration of Technical Supervision on 1991-08-15, implemented on April 1, 1992
GB/T3789.21---91
6.2 Adjust the first grid voltage to make the anode current reach the specified value, and read the first grid voltage value. 6.3 If the anode maximum dissipation power is exceeded or the anode dissipation power is greater than 10kW during the test, the pulse method test in GB/T 3789.14 is allowed.
