432A Power Meter with Thermistor Mount (50 Mhz to 12 GHz).
Quantity 5 - Location: Undergraduate
Lab.inv #
High accuracy over a wide
temperature range is featured on the 432A Power Meter. By measuring the output
voltage of the thermistor bridges and computing the corresponding power, even
higher accuracy of ±0.2%, ±0.5 ”W can be obtained. Accuracy can be maintained
on even the most sensitive range because the error due to thermoelectric effect
is reduced to a negligible level. The unit is an automatic, self-balancing
power meter for use with temperature-compensated thermistor sensor. Power
Range: 7 Ranges with full-scale readings of 10, 30, 100, and 300 ”W, 1, 3, and
10 mW Calibrated in dBm (-20 dBm to +10 dBm) Requires 478A or 486-series
Thermistor Mount.

436A Power Meter with Two Power Heads (50 MHz to 18 GHz).
Location: Undergraduate Lab.inv #
The capability, accuracy,
quality, and reliability have made the 436A Digital Power Meter one of the most
widely used digital power meters throughout the industry. Versatility is
provided with a frequency range of 100kHz to 18GHz at -70 dBm (100 pW) to +35
dBm (3 W), (depending on the power sensor used, sold separately). Accuracies
are as follows. Watt mode: ±0.5% in ranges 1 through 4, ±1% in range 5; dBm
mode: ±(0.02 dB +0.001 dB/șC) in ranges 1 through 4, ±(0.04 dB ±0.001 dB/șC) in
range 5; dB (REL) mode: ±(0.02 dB ±0.001 dB/șC) in ranges 1 through 4, ±(0.04
dB ±0.001 dB/șC) in range 5. Response times (0 to 99% of reading): Range 1:
<10 S, Range 2: <1 S, Ranges 3 through 5: <1 mS. Requires power sensor
HP
5342A Frequency Counter (10 Hz to 18 GHz).
Location:
Undergraduate Lab.inv #
The
5342A Frequency Counter provides automatic frequency measurement to 18GHz in a
highly portable package. Selectable input attenuation of 50 ohms and 1 Mohm.
Two input frequency ranges: 10Hz to 500MHz & 500MHz to 18GHz. The 5342A is
particularly useful in the communication field since it can tolerate an FM
carrier frequency of up to 50MHz peak to peak. Because it utilizes
microprocessor technology, the keyboard allows you to perform various math
functions to allow for such things as IF offsets. An 11-digit display is
sectionalized for easy readout to 1Hz resolution.
