A precision Power Meter with comprehensive GPIB facilities for ATE requirements and standard
bench applications
Counters & Power Meters
6960B RF Power Meter
• Extensive frequency coverage:
30 kHz to 46 GHz
• Wide dynamic range: -70 dBm (100 pW)
to +44 dBm (25W)
• Fast response on GPIB of 25 ms
• Auto averaging with manual override
• Both 50 Ů and 75 Ů sensors
• Low sensor VSWR reduces measurement
uncertainty
• Sensor linearity correction for improved
accuracy
• Maximum hold facility
• Optional DC operation
• Non-volatile memory
The 6960B RF Power Meter is a high accuracy
instrument which together with its associated
power sensors provides measurements at frequencies
from 30 kHz up to 46 GHz over a wide range of
power levels. Its numeric keyboard enables easy
manual control while full GPIB implementation
with SRQ mask and trigger modes make it the logical
choice for fast ATE systems.
Meter Accuracy
The 6960B features an instrumentation accuracy of
better than ±0.5% in linear mode and ±0.02 dB in
logarithmic mode. A special auto zero circuit digitally
stores the zero offset for each of the five ranges,
thus reducing zero carry over errors to ±0.03% and
providing a zero accuracy of ±1% of FSD on the
most sensitive range for any sensor type.
High Accuracy
All power sensors are provided with detailed calibration data to
0.01% resolution. In addition to Calibration Factor data, each sensor
is individually calibrated for linearity. When entered into the power
meter, this data reduces linearity errors to less than ±0.5% even on
the highest range.
Precision Calibration Attenuators
The 6920 series of high sensitivity power sensors are supplied with
a precision 30 dB attenuator for calibrating to the internal power reference.
These attenuators have an accuracy of ±0.05 dB at 50 MHz
to provide high calibration accuracy.
Duty Cycle Correction
Although the 6960B is a true average power measuring instrument, it
may still be used for pulsed power measurements. The duty cycle of
the signal to be measured may be entered in the range 100 to 0.001%.
The power meter calculates the peak power by dividing the measured
average power by the duty cycle.
Relative Measurements
The dB REL key enables the measurement of high powers by entering
the calibrated value of an attenuator or coupler directly as a negative
number. Positive relative values to account for amplifier gains
can also be entered. The dB offset facility may be used with linear
units so that transmitter output powers can be displayed in Watts.
Two Power-Up Modes
The instrument is provided with two power-up modes. For production
line testing, or applications in power monitoring at unattended sites,
power-up mode 2 returns the instrument to its previous settings after
switch-off or a power failure. Power-up mode 1 sets all the instrument
functions to default values.
