* All measurements marked with an asterisk (*) may be performed con-
tinuously, or in a synchronous, triggered mode. When triggered, these
measurements may be made at a single time offset relative to the trigger,
or over a defined time interval. The time offset or interval may be before
or after, or may span the trigger interval.
Channel Math: Displays the ratio, sum (power sensors) or difference (voltage sensors)
between channels or between a channel and a reference measurement
(Modulated and CW modes only).
Trace Averaging: 1 to 4096 samples per data point.
Panel setup storage: 4 complete setups.
Measurement rate (via GPIB): Greater than 200 two-channel measurements per second, neglecting bus
master overhead, or 500 single-channel measurements per sec.
1.4.6 Sensor Characteristics
CW Power Sensors
Power Detection Technique: Dual diode, single diode or thermo-electric.
Internal Data: Frequency and linearity calibration tables, frequency range, power range,
sensor type, serial number and other sensor dependent information are
stored in EEPROM within the sensor cable or in a cable-adapter for use
with existing CW sensors.
Peak Power Sensors
Power Detection Technique: Dual diode with selectable detector bandwidth.
Signal compression: The use of logarithmic signal compression circuitry in the sensor enables
the instrument to measure and analyze changes in power exceeding 60
dB in a single range.
Internal Data: Frequency, linearity and temperature calibration tables, frequency range,
power range, sensor type, serial number and other sensor dependent
information are stored in EEPROM within the peak power sensor.
Sensor Cable: The sensor cable is detachable from both sensor and instrument. The
standard cable length is 5 feet. Optional cable lengths are 10, 20, 25, and
50 feet. Additional cable length will affect measurement bandwidth.
RF Voltage Sensors Dual diode detector.
