Is there a problem updating firmware using USB interface?
An intermittent problem occurs with firmware updates using the USB interface with several of the
hand held test instruments. The list of instruments includes the MS2024A, MS2026A, MS2034,
MS2036A, MS2717A/B, MS2718B, MS2719B, MS2721A/B, MS2723B, MS2724B, MS8911A/B,
MT8220A and MT8222A. After the update is completed, the instrument may fail to boot properly.
If you have an instrument that fails to boot after a failed firmware update, use the following steps
to resolve the problem.
1. Close Master Software Tools and then re-open it.
2. Power off the instrument. Connect it via Ethernet to your local network or directly to your
PC using an Ethernet cross-over cable.
3. Power up the instrument into bootstrap mode. Hold the
1st
,
3rd
and
5th
soft keys,
located right of the display directly below the
"Esc"
key, then press the
Power
button.
Keep the 3 soft keys pressed until the Anritsu logo appears on the display. The Bootstrap
screen will appear after a few seconds.
