Inputs and outputs

All front panel connectors can be moved to rear with Option 1EM.

Transit case

Part number 9211-1296

 

 

10 MHz input

Accepts a 1, 2, 5, or 10 MHz ±10 ppm [standard timebase]

 

or ±1 ppm [high-stability timebase] reference signal for

 

operation with an external timebase. Nominal input

 

level –3.5 to +20 dBm, impedance 50 ohms.

 

[BNC, rear panel]

10 MHz output

Outputs the 10 MHz reference signal. Level nominally

 

+3.9 dBm ±2 dB. Nominal output impedance 50 ohms.

 

[BNC, rear panel]

Alternate power input

Accepts CMOS1 signal for synchronization of external

 

data and alternate power signal timing. The damage

 

levels are –0.5 to +5.5 V. [Auxiliary I/O connector,

 

rear panel]

Baseband generator

Accepts 0 to +20 dBm sinewave, or TTL squarewave,

reference input

to use as reference clock for the baseband generator.

 

Phase locks the internal data generator to the external

 

reference; the RF frequency is still locked to the 10 MHz

 

reference. Rate is 250 kHz to 100 MHz, 50 ohms

 

nominal, AC coupled. [BNC, rear panel]

Burst gate input

The burst gate in connector accepts a CMOS1

 

signal for gating burst power in digital modulation

 

applications. The burst gating is used when you are

 

externally supplying data and clock information. The

 

input signal must be synchronized with the external data

 

input that will be output during the burst. The burst

 

power envelope and modulated data are internally

 

delayed and re-synchronized. The input signal must be

 

CMOS high for normal burst RF power or CW RF output

 

power and CMOS low for RF off. The damage levels

 

are –0.5 to +5.5 V.

 

This female BNC connector is provided on signal

 

generators with Option 601 or 602. On signal generators

 

with Option 1EM, this input is relocated to a rear panel

 

SMB connector. With Option 401, this connector is used

 

for the even second synchronization input.

Coherent carrier output2

Outputs RF modulated with FM or FM, but not IQ,

 

pulse or AM. Nominal power –2 dBm ±5 dB. Nominal

 

impedance 50 ohms. Frequency range from > 250 MHz

 

to 4 GHz. For RF carriers below this range, output

 

frequency = 1 GHz – frequency of RF output. Damage

 

levels 20 VDC and 13 dBm reverse RF power.

 

[SMA, rear panel]

1.Rear panel inputs and outputs are 3.3 V CMOS, unless indicated otherwise. CMOS inputs will accept 5 V CMOS, 3 V CMOS, or TTL voltage levels.

2.Coherent carrier is modulated by FM or FM when enabled.
