Output type:
Floating or grounded, HP-IB programmable.
Maximum float voltage (signal+float):
1OV
peak maximum
Zero-crossing outputs (available in Channel Config mode
only):
For each channel, a TTL-compatible zero-crossing
from high or low side to chassis ground.
output and polarity output are provided. The zero-crossing
output pulses high for approximately 600 ns each time the
channel phase
goes
through
Oo
or MOO. The polarity output
is high for phases of
Oo
to 180°, low for 180° to 360O.
These outputs do not reflect any user-specified phase offsets.
External timebase input:
10
MHz accepted at a nominal level
of 0.1 to 5V peak, automatic switching.
Timebase output:
Output level
>O
dBm (0.3V peak) into a 50Q
load. Output signal will be the internal timebase unless an
external timebase
is
connected to the external timebase
input. When an external timebase is connected, it will be
routed to the timebase output connector.
