7. it is used for the oscillograph security measuring device of satellite electric signal interface testing as claimed in claim 1, it is characterised in that
Welded between electric connector and banana jack on the signal converting test platform by wire, above each banana jack
There is the contact sequence number of the banana jack, the contact sequence number is the contact sequence in the electric connector where satellite electric signal to be tested
Number, only electric signal to be measured on signal testing line and ground wire p-wire insertion signal converting test platform need to be corresponded to contact during test
Banana jack.
8. it is used for the oscillograph security measuring device of satellite electric signal interface testing as claimed in claim 1, it is characterised in that
The signal record reappears terminal by the remote controlled oscillograph of netting twine, can be by the Wave data of the satellite electric signal of test
Real-time display is carried out, original test data is subjected to local record, can be without mistake after secondary satellite electric signal interface testing terminates
Very reappear test scene；In real time record or afterwards in reconstruction processes can to the normal or unusual waveforms of satellite electric signal to be measured and
Its details picture is preserved, printed.
A kind of 9. oscillograph security measurement method for satellite electric signal interface testing, it is characterised in that comprise the following steps：
When carrying out satellite electric signal interface testing, the electric connector where measured signal is first connected to signal by transit cable and turned
Connect the electric connector on test platform, whole signal contacts on signal converting test platform are converted into the banana plug of single contact
Hole, banana jack are one-to-one with the signal contact in measured signal electric connector；Then by signal converting test platform
Banana jack corresponding to the signal wire and ground wire of upper measured signal connects the banana plug of signal testing line and ground wire p-wire respectively
Head；Then oscilloprobe is connected with oscillograph, after connection finishes, oscillograph powered up, reappeared eventually using signal record
End carries out related setting using netting twine to oscillograph, finally powers up satellite, passes through the waveform and details of oscillograph observation signal
Feature, the waveform progress real time graphical that signal record reappears terminal-pair satellite electric signal to be measured is shown, to satellite telecommunications to be measured
Number normal and unusual waveforms and details picture preserve, printing；Meanwhile signal record reappears terminal also by satellite electric signal interface
The carry out of whole initial data of test is locally stored, tests the carry out panorama reproduction to test scene after terminating.
