4. AUXILIARY
INTERFACE
This male DB-9 connector is an RS-232 serial port that can be used
for controlling the signal generator remotely. It is functionally
equivalent to the GPIB connector.
5. DATA CLK OUT The TTL/CMOS-compatible DATA CLK OUT connector outputs a
clock signal for digital modulation data. This female BNC connector
is present only on instruments with Options UND or UN8. With
Option 201 you can select from several different output signals for
this connector
6. SWEEP OUT This female BNC connector provides a voltage range of 0 to +10 V.
When the signal generator is sweeping, the SWEEP OUT signal
ranges from 0 V at the beginning of the sweep to +10 V at the end of
the sweep regardless of the sweep width.
7. DATA OUT The TTL/CMOS-compatible DATA OUT connector outputs digital
modulation data sourced from an externally supplied signal at the
DATA input or from the internal pattern generator. This female
BNC connector is present only on instruments with Options UND or
UN8. With Option 201 you can select from several different output
signals for this connector.
8. TRIGGER OUT This female BNC connector outputs a TTL signal that is asserted
high at the start of a dwell sequence, or at the start of waiting for
the point trigger in manual sweep mode, and low when the dwell is
over, or when the point trigger is received, or once per sweep during
an LF sweep.
9. TRIGGER IN This female BNC connector accepts a TTL signal for triggering, such
as point-to-point in manual sweep mode or an LF sweep in external
sweep mode.
10. 10 MHz IN This female BNC connector accepts a −3.5 to +20 dBm signal from
an external timebase reference that is within 10 ppm (standard
timebase) or 1 ppm (high stability timebase).
11. 10 MHz OUT This female BNC connector provides a nominal signal level of
+7 dBm ±2 dB, and an output impedance of 50Ω. The accuracy is
determined by the timebase used.
