Clean correctly working Boonton 4300 power meter with six 51075 sensors (0.05 - 18GHz) and 6 cables. Suggested operation: A. If you have a problem or 4300 meter lockup either: (a) press ESCAPE, then SHIFT, RECALL, 0, Enter ... or ... (b) turn power OFF then ON. Generally all programming problems can be dealt with by presing ESCAPE, SHIFT, RECALL, 0, ENTER ... and starting over. B. For 6 channel rapid less accurate (within 0.20dB at 0dB)) calibration, first connect all 6 sensors to the meter with NO sensors connected to the CALIBRATOR or active source. Then turn the meter on. 1. Wait 5 seconds, then press: MULTI. After 2 minutes warmup press ZERO. Wait about 10 seconds. All 6 channels should indicate UNderRNG or a value (under -70dB). IF any sensors do not zero press ESCAPE and then go back to the beginning of this paragraph 1. Repeat this paragraph until all channels indicate UNderRNG or a low value (under -70dB) Note: The sensors are matched to within 0.2dB at 0 or -2dB. This meter has the basic 50MHz CALIBRATOR that is always turned on at 0.00dB output. Also note the front panel CALIBRATOR buttons are meant for the optional 30MHz variable calibrator and these burttons will not work on the installed 50MHz calibrator. (2) Press ZERO again to verify and wait 10 seconds. Connect CHANNEL 1 to CALIBRATOR. Channel 1 should read about -2.00dB (3) Press SHIFT, SET REF, -2.00 (pressing the minus sign is important), ENTER. Now when connected to the calibrator all sensors should read 0.00dB within 0.20dB (4) Optionally to store this convenient setup press SHIFT, STORE, 2, ENTER. The calibration factors are now stored. Leave all sensors connected. *** To read the 6 sensors in the future, turn on the 4300, wait 2 minutes, then press: SHIFT, RECALL, 2, ENTER. Then press MULTI. Then when connected to the calibrator all 6 sensors should read 0.00dB within about 0.20dB. If needed press ZERO with no sensors connected to the CALIBRATOR or active source. All sensors should read 0.00dB calibrator within 0.20dB ********* (C) For more accurate sensor calibration the sensors should be set individually. 1. All sensors should be connected. Turn on the meter, wait 2 minutes, Press ESCAPE. Then connect CHANNEL 1 to CALIBRATOR, then press SHIFT, SET CH, 1, ENTER. LOAD. 2. Connect CHANNEL 2 to CALIBRATOR. Then press SHIFT, SET CH, 2, ENTER. LOAD. 3. Connect CHANNEL 3 to CALIBRATOR. Then press SHIFT, SET CH, 3, ENTER. LOAD. 4. Connect CHANNEL 4 to CALIBRATOR. Then press SHIFT, SET CH, 4, ENTER. LOAD. 5. Connect CHANNEL 5 to CALIBRATOR. Then press SHIFT, SET CH, 5, ENTER. LOAD. 6. Connect CHANNEL 6 to CALIBRATOR. Then press SHIFT, SET CH, 6, ENTER. LOAD. To verify, connect CHANNEL 1 to CALIBRATOR, press SHIFT, SET CH, 1, ENTER. CHANNEL 1 reading should be 0.00dB within 0.02dB. THEN: To store this setup (convenient), press SHIFT, STORE, 1, ENTER. The calibration factors are now stored. Leave all sensors connected. *** To accurately read all 6 sensors in the future, turn on the 4300, wait 2 minutes, then press: SHIFT, RECALL, 1, ENTER. Then press MULTI. Then when connected to the calibrator any sensor should read 0.00dB within 0.10dB
