|
|
Weighting curves may be entered and applied to all tones generated.
|
|
|
New frequency ranges for sweeps and segments can be repeated in a sequence at different levels, e.g. UU+10U-10
|
|
|
Minor changes.
|

|
|
|
New waveforms for negative going sawtooths and double tones (requires oscillator EPROM updates to OSC13). Difference frequency distortion.
|
|
|
Test tape mode is now more tolerant of noise and glitches, FSK decoding on right channel, crosstalk measurements at different levels.
|
|
|
Sequence banks. LA101 Configurations T6 and S6. Printing channel difference graphs. User tolerances increased from 5 to 10. CSV results files. SR? remote command.

|
Remote results format tidied up, heading correctly positioned and time out error fixed.
|
|
|
Subtract referance curve facility introduced.
|
|
|
V6.3 did not permit the use of weighted frequency sweeps. This is corrected.
|
|
|
Sweep headroom modified to provide greater accuracy in certain test circumstances.
