No, I’m not asking which signal generator to buy but I am looking to get one again so I can start working on radios again. My question is why do most of the modern. Leader Lsg-16 Signal Generator Manual Leader Audio Signal Frequency Generator LAG 26 Used. 17 is substantially the. Sheets/Leader-3215-16_Datasheet.pdf Leader LSG. The model 3215 and 3216 standard signal generators use a synthesizer system for generating. These manuals for the Leader 3215 Generator. User Manual -- Leader. This is reversed of most of the other signal generators that might go to 20dB to -127dB.Nope. They go from +20 dBm to -127 dBm (or whatever). That's not the same as 20dB to -127dB. DBm means decibels relative to 1 milliwatt. DB is just a power ratio. It represents an actual value only when a reference level is given. Gains or losses can be stated in dB without a reference (e.g. The amp has 22 dB of gain). Attenuators are usually marked with the appropriate value in dB. For those values to be meaningful the device must match the design source and load impedances. - Leigh _________________ 73 de W3NLB Click 'Grebe Stuff' for Synchrophase info Last edited by on Jun Sun 30, 2013 5:29 am, edited 1 time in total. Yeah, I thought it was something crazy.so that's why I'm asking. For example look at the Panasonic VP-8174A specifications on the manual located here. It states that 'The output amplitude can be set in 1 dB increments between -19 to 99 dB.' Dvc6020 fisher manual. • This instruction manual describes using the 475 Field Communicator to set up and calibrate the instrument. For information on using ValveLink software with the instrument refer to ValveLink software help or documentation. You can also use Fisher ValveLink software or ValveLink Mobile software to setup, calibrate, and diagnose the valve and instrument. The Leader 3215/3216 manual states that it goes between '-29dBu to 126dBu.' So after you explaining how many watts that would be I take it that both numbers are negative. Is -19dB or -29dBu enough output to start with if I have a really out of alignment radio? _________________ Radio 1240, After the Fallout.Radio Free Chillicothe. 'The output amplitude can be set in 1 dB increments between -19 to 99 dB.' That's not a spec. It's a statement. Leader Signal GeneratorThe specs appear at the beginning of Section II. The first spec under RF Output is: 'Range: -10 to 99db EMF' The adjacent comments section says '0dB EMF = 1μV' The maximum output level is 99dB above 1μV = 1 * 10^(99/20) = 89mV (.089V). That's about 158 microwatts. This is completely different from the dBm values common used, which have a reference of 1 milliwatt into 50 ohms. The voltage required to dissipate 1 milliwatt in 50 ohms is 235mV (0.235V) approximately. Remember what I said. DB ratings are critically dependent on the reference. Also, never believe advertising hype. Always read the actual specification table. - Leigh _________________ 73 de W3NLB Click 'Grebe Stuff' for Synchrophase info.
