1. Overview The Highspeed Programmable Attenuator Models 6010/6011/6012/6013, the 6010 series, provide attenuation of up to 80dB in steps of 0.05 dB and a minimum program step time of 2µs. The four models cover a wide frequency range of 1.5GHz – 13.5GHz. The 6010 series offers high accuracy, stability and many features, yet are easy to use. Due to the favorable price/performance ratio, the 6010/6011/6012/6013 attenuators are put to use in a diverse range of applications.

3. Description of panels 3.1 Front panel ①POWER - Main power switch. ②READ CLOCK IN - READ CLOCK input terminal. Apply an external clock signal with a maximum of 500 kHz to this input. ③TRIG IN - Apply a TTL level trigger signal to this terminal when in BURST or GATE mode. Readout of attenuation data is triggered by rising edge (BURST mode) or when signal is TTL high (GATE mode). ④SYNC OUT - TTL level Output signal, indicates start of readout period when in program mode.
⑧READ CLOCK - Key for selection of program memory read clock frequency. ⑨READ MODE - Key for selecting BURST, GATE or FREE program execution mode. ⑩ATTEN - Key for setting attenuation values in manual mode. ⑪PROGM LENGTH - Key for setting the program memory length. ⑫SET UP - Key for interface configuration. ⑬FILTER - Key for setup of attenuator switching response time. ⑭PAUSE TIME - Used for setting of program pause time. ⑮ENTER - Used to confirm front panel entries ⑯ - Move cursor left.
3.2 Rear panel ①AC line input - Connector for supplying AC power to the instrument. Use the provided power cord to connect to a power outlet. The AC voltage range is 90 - 130V or 180 - 250V. Make sure that the supplied voltage is within this range. The AC receptacle also incorporates a fuse holder. Use a slow blow fuse of 1.5A for 90 - 130VAC, or a slow blow fuse of 0.8A for 180 - 250VAC operation. ②AC line voltage select switch - The switch is used to select 90 - 130VAC or 180 - 250VAC operation.
4. Operation 4.1 Manual and program mode - Select the attenuator control mode. The cursor on the screen moves to [MANUAL] or [PRGM] at positions indicated below when the key is pressed. [MANUAL] mode screen ＭＡＮＵＡＬ ２３．４５ｄＢ １０μｓ [PRGM] mode screen ＰＲＧＭ ５００ＫＨｚ Ｌ：１３１０７２ Ｐ：６．５５３５ｓ ＦＲＥＥ １０μｓ - Toggle between [MANUAL] and [PRGM] mode by turning the rotary knob ① [MANUAL] mode The attenuation value set by remains active.
4.3 FILTER - Set the attenuator switching response time. The cursor moves to the position indicated below when the key is pressed. This parameter can be set in either [MANUAL] mode or [PRGM] mode. [MANUAL] mode example: ＭＡＮＵＡＬ ２３．４５ｄＢ １０μｓ [PRGM] mode example: ＰＲＧＭ ５００ＫＨｚ Ｌ：１３１０７２ Ｐ：６．５５３５ｓ ＦＲＥＥ １０μｓ - Filter Response time can be entered in 1-3 steps in the range of 1 µs – 3 ms using the rotary knob. Note: Use the built-in filter to reduce switching transients.
ＰＲＧＭ ５００ＫＨｚ Ｌ：１３１０７２ Ｐ：６．５５３５ｓ ＦＲＥＥ １０μｓ - Move the cursor using cursor keys, and set a value in the range of 8 - 131072 using the rotary knob. It is provided, however, that the upper limit depends on the date length in the program memory. - Press the < key to move towards the most significant digit and press the > key to mode towards the least significant digit. 4.6 PAUSE TIME - The pause time is defined as the interval between readout periods.
② When [CLOCK] is selected the main screen is displayed and the cursor moves to the position indicated below. ＰＲＧＭ ５００ＫＨｚ Ｌ：１３１０７２ Ｐ：６．５５３５ｓ ＦＲＥＥ １０μｓ - Move the cursor using the cursor keys and set a value in the range of 0 - 65535 using the rotary knob. The cursor moves towards the most significant digit when < is pressed and towards the least significant digit when the > key is pressed. - Note: The applicable clock signal is what was selected by READ CLOCK.
① When [FREE] is selected, the program is read (i.e., run) and a delay of the pause time is created. This is repeated continuously. ② When [GATE] is selected, the program read and pause times are repeated while the signal input to terminal TRIG IN is TTL High or while the is pressed (and held). ③ When [BURST] is selected, program read is executed at the rising edge of the signal applied to terminal TRIG IN or when the key is pressed. The pause time value is ignored. 4.

A command consists of the ASCII letters for the command and a data part. There is no blank between the command and the data part.
Each attenuation value is represented by one 16 bit word. The hexadecimal code for this word is coded as followed: ８６４０ Controls the SyncOut 8h: Sync pulse TTL High Fh: Sync pulse TTL Low Other values are not used Attenuation value: three Hex digits. Conversion: = Real ATT level(dB)／0.05 1h represents 0.05dB, 640h represents 80dB Each data word is transferred in the order of Low Byte first, High byte second. 80dB or 8640h would be transmitted as 4086h.
