In-line edit mode:
Audio, Channel Status and Valid bit may be
independently edited or passed through
Generator 2:
Audio function:
fs/4 sine, Jtest (cable-jitter stimulator), PRS
(pseudo-random sequence, white noise);
Channel Status:
Professional or Consumer, with correct fs and
CRC
Jitter generation:
Function: PRS-H (wide-band noise), PRS-L
(audio-band noise), fs/8 sine, long-cable-
simulation
Amplitude P-P: 0 to 3UI/8 in UI/8 steps,
(20.3ns steps at fs=48kHz); UI/12 steps at
fs=32kHz
Amplitude accuracy: ±10%

mode:
Jitter generation can be added to the
incoming signal
CHANNEL CHECKER:
Monitors any AES3 transmission medium and logs any bit-errors against time
Sub-frames tested:
A, B or both
Word-length:
16, 20 or 24-bit
Time-stamp range:
1000 hours
WATCHDOG:
Monitors a selectable range of carrier and data parameters and logs fluctuations
Selectable parameters:
Carrier fail/relock, biphase/parity error, eye-
width<50%, incorrect block-length/carrier
phase, audio-band detection on carrier, fs
(sampling-rate) base-value and accuracy,
Audio-bit activity (main, low-main and
auxiliary), Valid bit, User bit activity, Channel
Status: Professional/Consumer, emphasis,
sub-frame match, CRC errors, copy-
protection, channel mode;
Time-stamp range:
1000 hours
