WFM7200 Waveform Monitor v3.0.X Release Notes 3
Release notes
General limitations
This release has the following general limitations. Topics are listed in alphabetical
order.
Dolby operation with
Option DPE
For listening mode selections other than FULL or EX, clipping may
occur. For example, if the Dolby Digital input is 3/2 with full-scale test
tones and Stereo listening mode is selected, clipping will likely occur.
To avoid clipping, choose either compression mode, Dialnorm+Line or
Dialnorm+RF in CONFIG > Audio Input/Outputs > Dolby D (AC-3) Setup >
Dialnorm&DynRng.
When in Channel Mode 2/2 and Phantom Listening Mode, the Surround
Sound display (AUDIO tile) shows the Ls and Rs levels attenuated by 3 dB
instead of displaying at full amplitude for this channel mode/listening mode
combination.
When in Channel Mode 3/0 and 3-Stereo Listening Mode, the Surround
Sound display (AUDIO tile) shows the C level attenuated by 3 dB instead
of displaying at full amplitude for this channel mode/listening mode
combination.
The Dolby E/Dolby Digital decoder will pass through PCM audio at 48 kHz
frequencies or less. Audio frequencies above this will not pass through and
may cause noise or distortion on both the bars and the audio outputs. If PCM
audio at frequencies greater than 48 kHz is used, choose either AES A or
B as the input source.
Firmware update to
version 3.X
The first time the instrument firmware is updated to version 3.X, the upgrade
process must be run twice in order for the firmware to be properly installed.
Subsequent upgrades will require only one attempt to upgrade the firmware.
If you are updating firmware from 2.X to 3.X via USB, after the instrument
reboots, you may have to remove and reinsert the USB flash drive to complete
the update.
Firmware update with any
Dolby option
When updating the instrument firmware to 3.0.X and Option DPE is installed, do
not cycle the instrument power until the Power-on diagnostic screen is cleared
and the User interface is fully running. If the Instrument Fault LED is lit (red
Power/Standby button), an additional instrument reboot is required. This may be
performed by pressing the Power/Standby button. When the upgrade is complete,
the Dolby firmware version will be 2.1.2.1. You can confirm the version on your
instrument from the CONFIG > Utilities > SW Version menu.

Release notes
Incompatible operation When applying 3 Gb/s signals to any instrument that does not support the
signal formats, the unit indicates that the signal input is not standard. Applying
unsupported video signals may result in a frozen PICT display.
SNMP messages Commands returning the audCurOutput OID return the string “Embed 7 & 8” for
embedded audio channel pairs 9 & 10, 11 & 12, 13 & 14, and 15 & 16.
Sweep The waveform style must be set to Overlay to get 2 line or 2 field sweep.
USB Always press the MAIN button and select USB Status to safely “Unmount”
and remove the USB memory device from the USB port. You risk permanent
loss of any files saved on the USB device if you do not use the “Unmount”
feature.
If there are more than 32 files saved in a Capture or Presets directory on the
USB device, you can only view the first 32 files.
Waveform mode cursor for
XYZ color space
The voltage cursors are given in millivolt scale, but the XYZ color space is
referenced in hex scale. To see the values for 000 to FFF, change the graticule
settings to max and percent.
Web browser The Web browser applet will not resize when running in some versions of
the Netscape browser and in some non-Windows Operating Systems (for
example, Solaris).
We recommend using Java Runtime Engine (JRE) version 1.6 or above.
