Test Instructions for Passive Components of Tianda Scalar Network (td3611c) Test Instructions for Passive RF Components (TD3611C Scalar Network Analyzer) 1. Turn on the instrument, press the \"Reset\" key, then press the \"Confirm\" key to reset the instrument, and preheat for 30 minutes. Note: ① This step is generally not necessary, only in special circumstances. ② Preheating is generally sufficient for 10 minutes. 2. Set the \"RF Power\" to +8dBm (75Ω) or +10dBm (50Ω) or 0dBm. Press the \"RF Power\" key, then press the \"8\" key and the \"Confirm\" key. At this time, the power bar on the bottom line of the screen shows 8.0 dBm. When measuring passive RF devices, it is best to set the RF power to 0 dBm. When measuring large dynamic passive RF devices, set the RF power to +8dBm (75Ω) or +10dBm (50Ω). 3. Set the test frequency Set the test frequency according to the needs of the test. For example, set the start frequency to 5MHz and the end frequency to 1000MHz. Press the \"Start/Stop\" key, the cursor lights up at the start, press the \"5\" key, and then press the \"Confirm\" key. Press the \"▼\" key, the cursor lights up at the end, press the \"1000\" key, and then press the \"Confirm\" key. The bottom line of the screen displays the set start and end frequencies. IV. Calibrate the instrument (zero calibration) The instrument can be calibrated only after setting the RF power, start and end frequencies. If the RF power or start and end frequencies are changed during the test, the instrument needs to be recalibrated. 1. Transmission calibration, the connection diagram is as follows: Test cable a. Turn on channel A and turn off channel B. b. Press the \"Calibrate\" key, then press the \"Confirm\" key, and wait until \"Calibration Completed\" is displayed on the right side of the screen. Note: For transmission calibration, the test cable to be tested must be connected between the bridge and the detector, and short-circuited directly through the adapter. 2. Return loss...
