Anritsu MG3690A manual Ext Alc, Pulse Modulation

EXT ALC IN

Provides for leveling the RF output signal externally with either a detector or power meter. Signal requirements are shown in the RF Output specifications.

RF OUTPUT

Provides for RF output from 50Ω source impedance. K Connector, female. Option 9 moves the RF Output connector to the rear panel.

10 MHz REF IN

Accepts an external 10 MHz ±100 Hz, 0 to +20 dBm time-base signal. Automatically

AUX I/O (Auxiliary Input/Output)

Provides for most of the rear panel BNC connections through a single, 25-pin, D type connector. Supports master-slave operation with another synthesizer or allows for a single- cable interface with the Model 56100A Scalar Network Analyzer and other Anritsu instruments. (see figure below)

SERIAL I/O (Serial Input/Output)

Provides access to RS-232 terminal ports to support service and calibration functions and master-slave operations.

IEEE-488 GPIB

PULSE VIDEO OUT

Provides a video modulating signal from the internal pulse generator, Option 24.

AM IN

Accepts an external signal to amplitude modulate the RF output signal, Option 14. 50Ω impedance.

FM/Φ M IN

Accepts an external signal to frequency or phase modulate the RF output signal, Option 12. 50Ω impedance.

disconnects the internal high-stability time- base option, if installed. 50Ω impedance.

10 MHz REF OUT

Provides a 1 Vp-p, AC coupled, 10 MHz signal derived from the internal frequency standard. 50Ω impedance.

HORIZ OUT (Horizontal Sweep Output)

Provides 0V at beginning and +10V at end of sweep, regardless of sweep width. In CW mode, the voltage is proportional to frequency between 0V at low end and +10V at the high end of range. In CW mode, if CW RAMP is enabled, a repetitive, 0V to +10V ramp is provided.

EFC IN

Provides the capability to frequency modulate the internal crystal oscillator, allowing phase locking the synthesizer inside an external lock loop. Specifications on page 2.

Provides input/output connections for the General Purpose Interface Bus (GPIB).

mmW BIAS

Provides the bias for the external waveguide multipliers for coverage up to 110 GHz.

RF, LO, IF

Provides access to an internal IF up- conversion mixer, Option 7.

PULSE TRIG IN

Accepts an external TTL compatible signal to pulse modulate the RF output signal or to trigger or to gate the optional internal pulse generator. Available with Option 13,

Pulse Modulation.

PULSE SYNC OUT

Provides a TTL compatible signal, synchronized to the internal pulse modulation output, Option 24.

Aux I/O pins:

AM OUT

Provides the amplitude modulation waveform from the internal LF generator, Option 23.

FM/Φ M OUT

Provides the frequency or phase modulation waveform from the internal LF generator, Option 23.

SCAN MOD IN

Accepts an external signal to scan modulate the RF output signal, Option 20. High Impedance.

POWER MONITOR IN

Accepts an external detector for power monitoring, Option 8.
