Product Summary3440a.jpg (15865 bytes)
NIST traceable True RMS: 100 µV to 30 mV; 10 kHz to 1.2 GHz (usable to 2.4 GHz)
Volts and dB Operation: Measures 100 µV to 300 V and -60 dB to +60 dB
Accuracy ± (1% FS + 1% reading) to 150 MHz, NIST traceable
RF detector probes field replaceable
Calibrated to 10 kHz to 1.2 GHz. Usable <10 kHz to >2.4 GHz
True RMS to 30 mV, changing gradually to peak detector calibrated in rms of a sine wave above 30 mV.
1 mV full scale to 3 V full scale in eight ranges: 1/3/10 scale sequence.
Optional Model 1340A divider extends range to 300 V.
-59 dBm to +23 dBm in eight 10 dBm steps. Reference: 0 dBm=1 mV into 50 W .
Note Optional Model 1340A divider extends range to +63 dBm. Contact factory for price and delivery on other dB references and scales.
Crest Factor (True RMS Ranges)
Temperature Effect (Outside 15°C to 25°C reference conditions)
Three scales and anti-parallax mirror are provided. Top scale is 0 to 10 and is 4.4 inches long. The middle scale is 0 to 3. The bottom scale is -10 to +3 dB.
Indicator Unrest (1 mV FS range)
Unrest of the meter pointer will be <±1% FS above 500 µV indication, <±2% FS between 300 µV and 600 µV and <±5% from 100 µV to 300 µV.
Less than 1 sec on the 3 mV to 3 V ranges; 3 sec on the 1 mV range. Meter recovers to within 10% of final indication within 1 min after removal of 3 V rms overload on 1 mV range.
A front panel switch selects normal and slow response times when measuring input signals that are stable, amplitude variable, or noisy.
A detachable probe containing the RF detector is provided. Accessories provided with the probe are a convenience spring tip adapter with ground clip and a 50 W terminated adapter mating with BNC or Type N connectors. The shielded probe cable is 4 ft (1.2 m) long and terminated in a locking quick-disconnect connector at the front panel.
The VSWR using the probe with the non-loading Tee connector in a 50 W system is no greater than 1.3 from 10 kHz to 1.2 GHz.
The probe requires less than 1.9 nW of input power at 300 µV input voltage when used with the non-loading Tee connector in a 50 W system.
The probe input is fully protected to 10 V ac on all ranges and frequencies. Maximum DC input is ±400 V on all ranges.
A rear panel set of binding posts provides >+1 V dc full scale deflection on "10" ranges and 0.948 V on "3" ranges into an open circuit. Source impedance is 1000 W (±5%). The dc output is short-circuit proof. Output voltage is directly proportional to meter deflection and the rms value of the probe input voltage, which allows for use as an ac to dc converter.
A REL REF control allows continuously variable reduction of sensitivity by a minimum of 3.3 dB. It permits 0 dB reference level change and is useful in setting the meter to a convenience scale mark when performing relative gain or loss measurements. A detented position is provided for normal measurements.
A fused power selector safety switch and receptacle on the rear panel selects one of four ac operating voltage ranges. Input power: 20 VA maximum.
90 to 108 V (100 V); 48 to 420 Hz, 103 to 130 V (115 V); 48 to 420 Hz
198 to 238 V (220 V); 48 to 420 Hz, 216 to 260 V (240 V); 48 to 420 Hz
Temperature: Storage: -54°C to +85°C, Oper.: 0°C to 50°C, Ref.: 15°C to 25°C
Humidity: 0 to 80% RH to 50°C without condensation, 0 to 95% RH to 35°C
