GENERAL INFORMATION

Performance data
Carrier frequency
Range
10 kHz to 1.35 GHz (2050T);
10 kHz to 2.7 GHz (2051T);
10 kHz to 5.4 GHz (2052T).
In digital and vector modes the lowest frequency is 10 MHz and for
2050T the highest frequency is reduced to 2.7 GHz.
Selection
By keyboard entry of data. Variation by

keys and by rotary
control.
Indication
11 digits with annunciators
Resolution 0.1
Hz.
Accuracy
As frequency standard.
Phase incrementing
The carrier phase can be advanced or retarded in steps of 1.5° using
the rotary control.
RF output
Range (analog mode)
In analog modulation or CW mode range is -144 dBm to +13 dBm.
Maximum guaranteed output level above 2.7 GHz is +11 dBm.
When AM is selected the maximum output level reduces linearly with
AM depth to +7 dBm at maximum AM depth.
Range (digital or vector mode)
−
138 dBm to +6 dBm peak envelope power*.
RF output level is defined with PRBS modulation applied in digital
mode or with 0.5 V applied to either the I or Q input in vector mode.
*Maximum level is reduced to
−
6 dBm PEP when advanced digital
mode is selected.
Selectable overrange mode
Allows uncalibrated output levels to +19 dBm to be generated in
analog mode.
Selectable extended
hysteresis
Provides for uncalibrated RF level control with up to 24 dB range
without level interruption.

VSWR
For output levels less than 0 dBm:
Less than 1.25:1 to 2.2 GHz (return loss greater than 19.1 dB);
Less than 1.4:1 to 2.7 GHz (return loss greater than 15.6 dB);
Less than 1.5: 1 to 5.4 GHz (return loss greater than 14 dB).
Output protection
An electronic trip protects the generator output against reverse power
of up to 50 W from a source VSWR of up to 5:1.
