B.7 Sony/Tektronix Data Generator DG2020 (Berlin Version)
Module name: dg2020_b
Description: Sony/Tektronix Data Generator DG2020, used as pulser for the Berlin X-band spectrometer.
Timebase: between 5 ns and 100 ms
Maximum pulse voltage: between -2 V and 7 V
Minimum pulse voltage: between -3 V and 6 V
Difference between minimum and maximum pulse voltage must be not more
than 9 V and at least 0.5 V.
Pulse voltage resolution: 0.1 V
Trigger-in level: Between -5 V to 5 V
Trigger-in voltage resolution: 0.1 V
Trigger-in impedance: 50 Ohm (LOW
) or 1 kOhm (HIGH
)
Number of output connectors (POD): 12
Number of internal channels: 36
Due to some problems with the firmware of the device pulse sequences
always start with a state where the output of all connectors is the
minimum pulse voltage for the duration of the timebase (this also holds
for function/output channels declared as INVERTED
).
Controlled via: GPIB bus (IEEE 488).
In the GPIB configuration file use "DG2020_B"
as the device name,
'\n'
or 0xa
as the EOS character and set set-reos
,
set-xeos
and set-bin
to no
.
