3GHz Hand-Held Counter

Wide Frequency Range and High Resolution

The PFM3000 offers high sensitivity frequency measurement from 3Hz to more than 3GHz in two overlapping ranges. Period measurement is also provided from 8ns to 330ms.

The PFM3000 uses a continuous reciprocal measurement technique to provide high resolution at all frequencies with rapid update.It offers high sensitivity across the whole frequency range. A low pass filter can be selected to reduce high frequency signal noise at lower frequencies.

Large and Clear Display

Despite its compact dimensions, the PFM3000 incorporates a large 8 digit LCD. Annunciators are provided for measurement function, measurement time, overflow, trigger activity, low battery, and measurement units.

Bench-Top Use

The PFM3000 has the performance needed for many bench-top applications, and its built-in tilt stand sets the display at a convenient angle.

MEASUREMENT FUNCTIONS
Frequency (Range A)
Frequency Range	3Hz to 125MHz
Resolution	10-7Hz to 100Hz (see Note)
Frequency (Range B)
Frequency Range	80MHz to 3000MHz
Resolution	1Hz to 10kHz (see Note)
Period (Range A only)
Period Range	8ns to 330ms
Resolution	10-7ns to 1us (see Note)
Measurement Time
Selectable as 10s, 1s or 0.1s. (Note that for the 0.1s setting the effective measurement time is 0.3 seconds).
Resolution
The displayed resolution depends upon the measurement time and the input frequency. Eight digits (or nine using an overflow indication) are displayed for a 10s measurement time. Seven or eight digits are displayed for a 1s measurement time, and six or seven digits for 0.1s depending upon the input frequency. Usable resolution may be further reduced by noise, particularly at low frequencies.
Accuracy
Measurement accuracy is the sum of the timebase accuracy and measurement resolution plus one count.
TIMEBASE
Crystal Oscillator Frequency	10MHz
Initial Oscillator Adjustment Error:	± 2ppm (closed-case adjustable by user)
Oscillator Temperature Coefficient	Typically less than ± 0.3ppm/°C 18°C to 28°C, ±10ppm –20°C to 70°C
Oscillator Ageing Rate	<± 5ppm/year
OPERATING FUNCTIONS
Press to measure
With the power switch off, pressing any of the function select keys will power the instrument up in the corresponding function. The instrument will automatically switch off 15 seconds after the last key press.
Hold
Pressing the Hold key will stop further measurements being made and the current measured value will remain in the display until the Hold key is pressed again.
Noise filter
The Filter key controls a low pass filter, with a cut-off frequency of about 50kHz, to ensure more stable readings at low frequencies.
Signal activity indicator
When no input signal is detected the Trig indicator will be off, indicating that no measurement is possible. The gate time indicator flashes until the first measurement interval is complete.
INPUT SPECIFICATIONS
Input A
Input Impedance	1MΩ//20pF (AC coupled)
Frequency Range:	<3Hz to >125MHz
Sensitivity	Sinewave - 15mVrms 10Hz-125MHz
Input B
Input Impedance	50Ω (AC coupled)
Frequency Range	<80MHz to >3000MHz
Sensitivity	Sinewave - 15mVrms 80MHz-2GHz, 50mVrms to 3GHz
Maximum Input Voltage
Input A and Input B:	30Vdc; 30Vrms 50Hz/60Hz reducing to 1Vrms above 1MHz Note that the inputs will not be damaged if subjected to an accidental short-term connection to a 50/60Hz line voltage not exceeding 250V rms.
DISPLAY
No. of Digits	8 full digits plus overflow indicator for 8.5 digits
Size of Digits	11.5mm (0.45”)
Annunciators	15 annunciators
POWER REQUIREMENTS
Battery Type	9V PP3 alkaline

Excellent Frequency Counter

5.0

I was hesitant at first to purchase this unit because of its low price, no reviews, and from a company that I wasn't familiar with. But I needed a frequency counter that I could easily transport and use in the field, not a bulky bench top unit. I was quite pleased when I put this unit into service. I checked it against three different signal generators, including a very expensive 3 GHz Rohde & Schwarz. It is dead on accurate from its lowest range all the way up to its maximum and all points in between. It is so light that I hope it has some longevity, but it does come with a three year warranty. At this early time, I do recommend this frequency counter.
