5.1.1
Primary matrix and analog measuring bus
On this topic, see also
Configuring the R&S TS-PSAM for current or resistance measurements causes the
input of the measurement unit to become lowly resistive. An external voltage applied to
the input will therefore lead to a current flow through the instrument, which may destroy
the relays on the module. It is therefore strongly recommended to configure the R&S
TS-PSAM for “voltage measurement” before the input is connected with the test points.
Matrix relays
The stimulus and measurements can be cross-connected in any permutation through a
full matrix to a local analog bus (8-wires LABx). The discharge circuit can only be con-
nected to wires a1 and a2.
For the cross-connection of the relays matrix, there are two possibilities:
●
route functions
●
low-level-switching function
Route functions
Using the
rspsam_Connect
,
rspsam_Disconnect
and
rspsam_DisconnectAll
functions, you can control the following channels of the matrix:
Local analog bus:
ABa1, ABa2, ABb1, ABb2, ABc1, ABc2, ABd1, ABd2
DMM resistance measurement function:
DMM_HI, DMM_LO, DMM_SHI, DMM_SLO
Single components:
DCH_HI MU_HI, MU_LO, DCS_HI, DCS_LO, DCS_SHI, DCS_SLO
The "ABxy" channel names always indicate the services of the local analog buses,
independently from the bus coupling relays configuration
(
rspsam_ConfigureCoupling
). The route functions of the driver do not control the
bus coupling relay.
