Page 3: Introduction
Introduction The TF900 series includes the TF960 and TF930. These are portable, battery-operated, universal counters with a large 0.5" 10-digit liquid crystal display (LCD). The frequency range is from below 0.001Hz to over 6GHz (3GHz TF930) and measurement functions include frequency, period, ratio, pulse width and count. -

Specification Input Specifications Input A Configurable options Input coupling: AC or DC Input impedance: 1MΩ or 50Ω Attenuation: 1:1 or 5:1 Active edge: Rising or falling, or width high or low Low pass filter: Filter In (~50kHz cut-off) or Out Trigger threshold: Variable threshold for both DC and AC coupling Input Impedance:... - Page 5 Timebase Measurement Clock: 50MHz. Internal Reference oscillator: 10MHz TCXO with electronic calibration adjustment. Oscillator Temperature Stability: Better than ± 1ppm over rated temperature range. Initial Oscillator Adjustment Error: < ± 0.2ppm at 21ºC. Oscillator Ageing Rate: < ± 1ppm first year. Calibration adjustment range: >...
- Page 6 Accuracy Measurement accuracy is timebase accuracy + measurement resolution + 2 counts. Operating Facilities Noise Filter (Input A only*) The Filter key controls a low pass filter, with a cut-off frequency of about 50kHz, to assist in obtaining stable readings at low frequencies. Hold Pressing the Hold key will hold the current measured value in the display, with the Hold indicator on, until the Hold key is pressed again.
- Page 7 Safety & EMC: Complies with EN61010-1, EN60950-1 (Adapter/charger) & EN61326-1. For details, request the EU Declaration of Conformity for this instrument via http://www.aimtti.com/support (serial no. needed).

Page 8: Safety
Safety Universal Counter This instrument is Safety Class III according to IEC classification and has been designed to meet the requirements of EN61010-1 (Safety Requirements for Electrical Equipment for Measurement, Control and Laboratory Use). This instrument has been tested in accordance with EN61010-1 and has been supplied in a safe condition. -

Connections Front Panel Connections Input A For frequencies in the range 0.001Hz (DC coupled) to >125MHz. Input impedance selectable between 1MΩ//25pF and 50Ω. Maximum allowable input 1V (1:1 attenuation) or 4V (5:1 attenuation) for 1MΩ//25pF input; 1V above 300kHz for 50Ω input (AC coupled). Maximum input with respect to earth ground is 30V or 30V... -
Page 10: Manual Operation
Power-up and power-down operation for all possible combinations of conditions are detailed in the sections that follow. Safety Warning: The TF900 series are safety class III instruments by IEC classification. When the instruments are operated from their internal battery, AC adaptor or USB port of a portable (ungrounded) PC, all accessible parts will be at the same voltage potential as the outer of the N-type and BNC input sockets;... - Page 11 AC Adaptor Operation The AC adaptor is connected to the rear panel 1.3mm socket marked DC IN; only the AC adaptor supplied with the instrument should be used. When the AC adaptor is powered the red EXT POWER lamp will be lit, whether the instrument is on or off; if the battery is being charged the yellow CHARGING lamp will also be lit.
- Page 12 Input A Configuration Options The default configuration options for Input A at power-on are: AC coupling, 1MΩ input impedance, 1:1 attenuation, rising edge polarity and no filter; with the Threshold control set to mid-position a measurement should be possible with the majority of waveforms. Changes to the configurations will, however, be necessary for certain waveforms, e.g.
- Page 13 This setting should count most signals, but on very small signals some slight adjustment may be needed for maximum sensitivity. The usable adjustment range from this position is approximately ±50mV (1:1 attenuation) or ±200mV (5:1 attenuation). If DC coupling is in use then the feedback mechanism is disconnected and the threshold is directly adjusted by the control over the range of nominally 0 to 2V (1:1 attenuation) or 0 to10V (5:1 attenuation).
- Page 14 Function Selection – A input Pressing the FREQUENCY, PERIOD or WIDTH key will immediately set the instrument to that function; pressing and holding the key down for more than 1 second will change the function to COUNT, RATIO or DUTY respectively, the 2 function printed above the key in blue;...
- Page 15 Pressing the HOLD key will freeze the displayed measurement and the Hold annunciator will be shown; Hold is cancelled by a second press of the HOLD key. The measurement continues in the background while Hold is selected. Switching between FREQUENCY and PERIOD measurement on the same input, or switching between WIDTH, RATIO H:L and DUTY (Input A), will immediately convert the present measurement;...
- Page 16 Timebase and Other Accuracy Considerations The following is intended as a guide to determine the limits of measurement error. Internal Oscillator The instrument has an internal temperature compensated crystal oscillator (TCXO) which has been factory set from a Rubidium reference standard such that it is within ± 0.2ppm (parts per million) after warm-up in an ambient of 21ºC.

Page 17: Remote Operation
Remote Operation The USB interface allows the instrument to be controlled using serial communications via a computer’s USB port. The instrument is supplied with a disk containing drivers for various versions of Windows. Any driver updates are available via the TTi website, http://www.aimtti.com/support. The disk also contains a text file with information and details of the software installation procedure. - Page 18 Remote Command Format Serial input to the instrument is buffered in an input queue which is filled, under interrupt, in a manner transparent to all other instrument operations. The instrument will send XOFF when the queue is nearly full; XON will be subsequently be sent when sufficient space becomes available for more data to be received.
- Page 19 C Input Period* The new function is selected immediately and a new measurement is started. Set A Input to AC coupling. Set A Input to DC coupling. Set A Input to 1MΩ input impedance. Set A Input to 50Ω input impedance. Set A Input to 1:1 attenuation.
- Page 20 Threshold Level to centre position. Threshold Level to negative pulse position. Threshold Level to positive pulse position. These three commands are only included to maintain compatibility with the TF830 and are used to set the threshold level to one of three ‘preset’ positions available under remote control on that counter. ‘Centre’ is equivalent to the threshold level control at the midway 'AC' position.
- Page 21 Miscellaneous Commands *IDN? Returns the instrument identification in the form <name>, <model>, 0, <version><rmt> where <name> is the manufacturer’s name, <model> is the type of instrument and <version> is the revision of the firmware installed. Identify Query. Returns the instrument model number only. *RST Resets the instrument to its power-on default values and sets the Threshold Level to the midway ‘AC' position.
