Connected mode
As soon as the host PC application (R&S ROMES or R&S NESTOR) or customer
application based on the ViCom interface accesses the R&S TSME via the LAN inter-
face, the R&S TSME switches to connected mode .
After establishing the connection to the R&S TSME, the first thing the host PC applica-
tion does is to send the required application firmware to the R&S TSME. The
R&S TSME is then ready for measurement commands sent from R&S ROMES,
R&S NESTOR, or R&S ViCom.
The [STATE] LED is green.
Measuring mode
The instrument switches to measuring mode immediately after receiving any measur-
ing command from the host PC software.
In measuring mode the [STATE] LED blinks green (rapidly).
Standby mode
When you press the "On/Off" key on the rear panel of the R&S TSME, the instrument
switches to standby mode . Program execution on the instrument is stopped immedi-
ately, but the instrument is still under power connection. The [Power] LED is yellow, all
other LEDs are off.
If you remove the power supply in standby mode and reconnect it later, the R&S TSME
switches back to standby mode and does not automatically boot. You must press the
"On/Off" key first to start booting.
Error mode
If an error occurs during operation and no measurements are possible, the R&S TSME
falls into error mode .
The [STATE] LED turns red. If possible, warnings or errors are indicated in the "Device
Analysis Output" table of the R&S
TSME Device Manager (see Chapter 4.2, "Obtaining
Device Information" , on page 43).
The following diagram shows the order in which the R&S TSME goes through the vari-
ous instrument modes.
